File lstFile = new File(lstFileName).withWriter{out->
archivedFiles.each {out.println it.name}
}
archivedFiles is a List objects .. I am getting an error that says:
Cannot cast object with class 'java.util.ArrayList' to class 'java.io.File'.
I am only interested in writing out file names contained in the list to the NEWLY created file
That's beacuse the withWriter block is returning the last thing in the block by default (which is the archivedFiles list)
To do what you're trying to do, you'd need to do:
File lstFile = new File(lstFileName)
lstFile.withWriter{ out ->
archivedFiles.each {out.println it.name}
}
or this should work too:
File lstFile = new File( lstFileName ).with { file ->
file.withWriter{ out ->
archivedFiles.each {out.println it.name}
}
file
}

I have a csv file (UTF-8 with BOM) like this
NAME,F1,F2,
test1,field1,field2
test2,field1,field2
test3,field1,field2
test4,field1,field2
test5,field1,field2
test6,field1,field2
I would like to discard the first three lines and create new csv (UTF-8 with BOM)
NAME,F1,F2,
test4,field1,field2
test5,field1,field2
test6,field1,field2
I get some idea from the page and code this in JSR223 PreProcessor
def originalCsvFile = new File('g:/Workspace/1.csv')
def newCsvFile = new File('g:/Workspace/2.csv')
originalCsvFile.readLines().take(5).each {line ->
newCsvFile.withWriter('UTF-8') { writer ->
writer.writeLine line
}
}
The above code does not work.
It is better to put the new csv path to the variable, I want to get the variable in jmeter CSV Data Set Config
Do you realize that:
take(5) function returns 5 first lines of the list
newCsvFile.withWriter function overwrites the file with the new data each time it's being called
So I believe you're looking for copying and pasting something like this:
originalCsvFile.readLines().eachWithIndex { line, index ->
if (index == 0 || index > 3) {
newCsvFile.withWriterAppend('UTF-8') { writer ->
writer.writeLine line
}
}
}
More information on Groovy scripting in JMeter: Apache Groovy - Why and How You Should Use It
Not as elegant, perhaps, but this is how I would do it:
List li = originalCsvFile.readLines()
newCsvFile.append(li[0] + "\n", 'UTF-8') //headers
li[4..-1].each { newCsvFile.append(it + "\n", 'UTF-8') }
I have series of xml files placed in 2 separate folders as below. My objective is to read each file one at a time from both folders and apply xmlunit comaprison methods.
Folder1 : actual1.xml
actual2.xml
actual3.xml
Folder2 : compare1.xml
compare2.xml
compare3.xml
Part1: Am reading each file at a time from both folders by using below script. I welcome suggestions if there are more simpler methods to do this
log.info "**********Read files from Folder1************"
def xml_file1 = []
new File("D:\\GroovyTest\\Folder1").eachFile{ f ->
f (f.isFile()&& f.name.contains('.xml'))
{
def filename = f.name[0..-1]
xml_file1.add(filename)
log.info filename
}
}
if (xml_file1.size() <1)
{
testRunner.fail("No request files found")
}
log.info "**********Read files from Folder2************"
def xml_file2 = []
new File("D:\\GroovyTest\\Folder2").eachFile{ f ->
if (f.isFile()&& f.name.contains('.xml'))
{
def filename = f.name[0..-1]
xml_file2.add(filename)
log.info filename
}
}
if (xml_file2.size() <1)
{
testRunner.fail("No request files found")
}
Part2: Script to perform comparison for each combination of xml files contained in array xml_file1 and xml_file2.
Am actually stuck at this part as the below script works for single files if each xml file is kept in a string, but i have to pass an array as arguments since i have series of xml files to be compared. I get a run time error - groovy.lang.GroovyRuntimeException: Could not find matching constructor for: java.io.FileInputStream(java.util.ArrayList) error at line: 60
InputStream xml_stream1 = new FileInputStream(xml_file1)
String xml1 = getStringFromInputStream(xml_stream1)
InputStream xml_stream2 = new FileInputStream(xml_file2)
String xml2 = getStringFromInputStream(xml_stream2)
def factory = TransformerFactory.newInstance()
def transformer = factory.newTransformer(new StreamSource(new StringReader(xslt)))
StreamResult result_xml1 = new StreamResult(new StringWriter());
transformer.transform(new StreamSource(new StringReader(xml1)), result_xml1)
xml1 = result_xml1.getWriter().toString()
StreamResult result_xml2 = new StreamResult(newStringWriter());
transformer.transform(new StreamSource(new StringReader(xml2)), result_xml2)
xml2 = result_xml2.getWriter().toString()
XMLUnit.setIgnoreComments(true)
DifferenceListener differenceListener = newIgnoreTextAndAttributeValuesDifferenceListener();
DetailedDiff myDiff = new DetailedDiff(new Diff(xml1, xml2));
myDiff.overrideDifferenceListener(differenceListener);
myDiff.overrideElementQualifier(new RecursiveElementNameAndTextQualifier());
log.info "similar ? " + myDiff.similar()
log.info "identical ? " + myDiff.identical()
List allDifferences = myDiff.getAllDifferences();
for (Object object : allDifferences) {
Difference difference = (Difference)object;
log.info(difference);
}
Could someone also help me with methods to ignore empty tags during comparison?
Thanks
How to get values from properties file using Groovy?
I require to have a property file (.properties) which would have file names as key, and their destination path as the value. I will need the key to be resolved at runtime, depending on file that needs to be moved.
So far I am able to load the properties it seems but can't "get" the value from the loaded properties.
I referred to the thread : groovy: How to access to properties file? and following is the code snippet i have so far
def props = new Properties();
File propFile =
new File('D:/XX/XX_Batch/XX_BATCH_COMMON/src/main/resources/patchFiles.properties')
props.load(propFile.newDataInputStream())
def config = new ConfigSlurper().parse(props)
def ant = new AntBuilder()
def list = ant.fileScanner {
fileset(dir:getSrcPath()) {
include(name:"**/*")
}
}
for (f in list) {
def key = f.name
println(props)
println(config[key])
println(config)
def destn = new File(config['a'])
}
the properties file has the following entries for now :
jan-feb-mar.jsp=/XX/Test/1
XX-1.0.0-SNAPSHOT.jar=/XX/Test/1
a=b
c=d
Correct values are returned if I look up using either props.getProperty('a')
or,
config['a']
Also tried the code: notation
But as soon as switch to using the variable "key", as in config[key] it returns --> [:]
I am new to groovy, can't say what am i missing here.
It looks to me you complicate things too much.
Here's a simple example that should do the job:
For given test.properties file:
a=1
b=2
This code runs fine:
Properties properties = new Properties()
File propertiesFile = new File('test.properties')
propertiesFile.withInputStream {
properties.load(it)
}
def runtimeString = 'a'
assert properties."$runtimeString" == '1'
assert properties.b == '2'
Unless File is necessary, and if the file to be loaded is in src/main/resources or src/test/resources folder or in classpath, getResource() is another way to solve it.
eg.
def properties = new Properties()
//both leading / and no / is fine
this.getClass().getResource( '/application.properties' ).withInputStream {
properties.load(it)
}
//then: "access the properties"
properties."my.key"
Had a similar problem, we solved it with:
def content = readFile 'gradle.properties'
Properties properties = new Properties()
InputStream is = new ByteArrayInputStream(content.getBytes());
properties.load(is)
def runtimeString = 'SERVICE_VERSION_MINOR'
echo properties."$runtimeString"
SERVICE_VERSION_MINOR = properties."$runtimeString"
echo SERVICE_VERSION_MINOR
Just in case...
If a property key contains dot (.) then remember to put the key in quotes.
properties file:
a.x = 1
groovy:
Properties properties ...
println properties."a.x"
Properties properties = new Properties()
properties.load(new File("path/to/file.properties").newReader())
Just another way of doing it. Use this if it works for you. :)
Properties properties = new Properties()
//loading property file
File propertiesFile = new File(this.class.getResource('application.properties').getPath())
propertiesFile.withInputStream {
properties.load(it)
}
//Accessing the value from property file
properties.getProperty('userName')
With static method extension:
Properties.metaClass.static.fromFile =
{file -> new Properties().with{new File(file).withInputStream it.&load;it}}
def properties = Properties.fromFile('test.properties')
Groovy for getting value of property from "local.properties" by giving key.
Example- For finding value of this property's key is "mail.smtp.server"
In V5
ctx.getBean("configurationService")
configurationService = ctx.getBean("configurationService")
String value = configurationService.getConfiguration().getString("mail.smtp.server","")
In 1905
spring.getBean("configurationService")
configurationService = spring.getBean("configurationService")
String value = configurationService.getConfiguration().getString("mail.smtp.server","")
Hello I am using groovy 2.1.5 and I have to write a code which show the contens/files of a directory with a given path then it makes a backup of the file and replace a word/string from the file.
here is the code I have used to try to replace a word in the file selected
String contents = new File( '/geretd/resume.txt' ).getText( 'UTF-8' )
contents = contents.replaceAll( 'visa', 'viva' )
also here is my complete code if anyone would like to modify it in a more efficient way, I will appreciate it since I am learning.
def dir = new File('/geretd')
dir.eachFile {
if (it.isFile()) {
println it.canonicalPath
}
}
copy = { File src,File dest->
def input = src.newDataInputStream()
def output = dest.newDataOutputStream()
output << input
input.close()
output.close()
}
//File srcFile = new File(args[0])
//File destFile = new File(args[1])
File srcFile = new File('/geretd/resume.txt')
File destFile = new File('/geretd/resumebak.txt')
copy(srcFile,destFile)
x = " "
println x
def dire = new File('/geretd')
dir.eachFile {
if (it.isFile()) {
println it.canonicalPath
}
}
String contents = new File( '/geretd/resume.txt' ).getText( 'UTF-8' )
contents = contents.replaceAll( 'visa', 'viva' )
As with nearly everything Groovy, AntBuilder is the easiest route:
ant.replace(file: "myFile", token: "NEEDLE", value: "replacement")
As an alternative to loading the whole file into memory, you could do each line in turn
new File( 'destination.txt' ).withWriter { w ->
new File( 'source.txt' ).eachLine { line ->
w << line.replaceAll( 'World', 'World!!!' ) + System.getProperty("line.separator")
}
}
Of course this (and dmahapatro's answer) rely on the words you are replacing not spanning across lines
I use this code to replace port 8080 to ${port.http} directly in certain file:
def file = new File('deploy/tomcat/conf/server.xml')
def newConfig = file.text.replace('8080', '${port.http}')
file.text = newConfig
The first string reads a line of the file into variable. The second string performs a replace. The third string writes a variable into file.
Answers that use "File" objects are good and quick, but usually cause following error that of course can be avoided but at the cost of loosen security:
Scripts not permitted to use new java.io.File java.lang.String.
Administrators can decide whether to approve or reject this signature.
This solution avoids all problems presented above:
String filenew = readFile('dir/myfile.yml').replaceAll('xxx','YYY')
writeFile file:'dir/myfile2.yml', text: filenew
Refer this answer where patterns are replaced. The same principle can be used to replace strings.
Sample
def copyAndReplaceText(source, dest, Closure replaceText){
dest.write(replaceText(source.text))
}
def source = new File('source.txt') //Hello World
def dest = new File('dest.txt') //blank
copyAndReplaceText(source, dest) {
it.replaceAll('World', 'World!!!!!')
}
assert 'Hello World' == source.text
assert 'Hello World!!!!!' == dest.text
other simple solution would be following closure:
def replace = { File source, String toSearch, String replacement ->
source.write(source.text.replaceAll(toSearch, replacement))
}
I have a sample file like the following:
CREATE GLOBAL TEMPORARY TABLE tt_temp_user_11
(
asdfa
)
CREATE GLOBAL TEMPORARY TABLE tt_temp_user_11
(
asdfas
)
some other text in file
I want to convert this file into following:
CREATE GLOBAL TEMPORARY TABLE 1
(
asdfa
)
CREATE GLOBAL TEMPORARY TABLE 2
(
asdfas
)
some other text in file
So basically every TEMPORARY TABLE occurrence will have number appended to it.
So far I have the following groovy script:
int i = 0
new File ("C:\\Not_Modified").eachFile{file ->
println "File name: ${file.name}"
new File ("C:\\Not_Modified\\"+file.name).eachLine {line ->
if (line.indexOf("TEMPORARY TABLE")>0)
{
i++
}
}
println "There are ${i} occurences of TEMPORARY TABLE"
}
How can I change the text in the file? should I be writing to a different file?
btw, I have directory in my script because I will be working on lot of these type of files in a directory.
I should have opted perl for this task but wanted to give groovy a try.
I wrote a little function that works kind of like File.eachLine{} works but allows editing.
You can use it like this:
def n=1
modifyFile("filename"){
if(it.startsWith("CREATE GLOBAL TEMPORARY TABLE"))
return "CREATE GLOBAL TEMPORARY TABLE " + n++
return it // Re-inserts unmodified line"
}
This is pretty easy to code--whatever is returned from the closure is written out to the new file. If you want a different file, provide two filenames.
/**
* This will completely re-write a file, be careful.
*
* Simple Usage:
*
* modifyFile("C:\whatever\whatever.txt") {
* if(it.contains("soil"))
* return null // remove dirty word
* else
* return it
* }
*
* The closure must return the line passed in to keep it in the file or alter it, any alteration
* will be written in it's place.
*
* To delete an entire line instead of changing it, return null
* To add more lines after a given line return: it + "\n" + moreLines
*
* Notice that you add "\n" before your additional lines and not after the last
* one because this method will normally add one for you.
*/
def modifyFile(srcFile, Closure c) {
modifyFile(srcFile, srcFile, c)
}
def modifyFile(srcFile, destFile, Closure c={println it;return it}) {
StringBuffer ret=new StringBuffer();
File src=new File(srcFile)
File dest=new File(destFile)
src.withReader{reader->
reader.eachLine{
def line=c(it)
if(line != null) {
ret.append(line)
ret.append("\n")
}
}
}
dest.delete()
dest.write(ret.toString())
}
}
I'm think you should write to different file, it's a good practice.
Put something like line below inside your if {} (instead of i++)
line = line.replaceFirst(/^(create temporary table) (.*)/, "\$1 table${++i}")
and then, outside of your if write line variable into outfile
BTW i'm think you better use ==~ in your if instead of indexOf
