I am trying to run a simple Groovy script that utilizes Geb to fetch a title. However, I receive an error:
Module [groovy-xml is loaded in version 4.0.2 and you are trying to load version 3.0.8
I user Groovy version 4.02. GROOVY_HOME is set; I installed Groovy via sdkman.
$ groovy -version

import geb.Browser
Browser.drive {
go "http://example.com"
println title
}
How to fix this?

Given the following code snippet:

Searching for solutions
I found this question: Groovy built-in REST/HTTP client? gave me a work around (not using http-builder).
Background on question
The UDEMY Groovy course https://www.udemy.com/course/apache-groovy/ provides some sample code during one of the lectures on a REST-based client in Groovy that uses the http-builder library.
The groovy and java version being used at the time of the course where
Java Version: 1.8.0_60
Groovy Version: 2.4.5
Gradle: 2.7
Maven: 3.3.3
Spring Boot: 3.0.M5
Spring Tool Suite (STS): 3.7.1.RELEASE-e4.5.1
On Windows 7 and Mac OS ?
i'm sure you have new version of groovy (for example 4.0.1) and http-builder library you are using is quite old.
starting from groovy 3.0 GPathResult class moved to another package: groovy.xml.slurpersupport.GPathResult
but according to error HTTPBuilder is looking for old package groovy.util.slurpersupport.GPathResult
option 1:
You have to downgrade groovy version
option 2: hacking
#Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.1')
import groovyx.net.http.*
//define empty class with old name to prevent failure
this.getClass().getClassLoader().getParent().parseClass '''
package groovy.util.slurpersupport
class GPathResult{}
'''
def http = new HTTPBuilder('http://httpbin.org')
//redefine xml parser to use xml slurper from a new package
//you don't need this if you are not going to work with xml
http.parser['application/xml']={HttpResponseDecorator r->
return new groovy.xml.XmlSlurper().parse(r.entity.content)
}
http.get(path:'/xml',query:[a:123]){resp,body->
println "status: ${resp.statusLine}"
println groovy.xml.XmlUtil.serialize(body)
}
Using #grab for the first time (new to groovy)
I understand it is meant to work "out the box."
However, when I add this to my class:
#Grab(group='commons-lang', module='commons-lang', version='2.4')
I get the following compilation error:
Caused by: java.lang.NoClassDefFoundError: org/apache/ivy/plugins/resolver/DependencyResolver
Groovy version is Groovy Version: 3.0.4 JVM: 11.0.1 Vendor: Oracle Corporation OS: Mac OS X
you have missing dependency or library ivy-2.4.0.jar
this library is a part of groovy-all artifact. check groovy-all.pom to see all groovy dependencies/features
so, you could setup dependency to groovy-all artifact in your project
or to a separate ivy-2.4.0.jar artifact if you don't want to include all groovy features into your project
Try adding this to gradle.build
configurations {
ivy
}
dependencies {
ivy "org.apache.ivy:ivy:2.4.0"
...
}
tasks.withType(GroovyCompile) {
groovyClasspath += configurations.ivy
}
I have the following Groovy test (not the real one, mind you) in a Gradle project (under src/test/groovy):
import javafx.scene.paint.Color
import org.junit.Test
class MyTest {
#Test
void test1() {
assert Color.AQUAMARINE != Color.BLUE
}
}
The build file is as simple as it gets and declares that I use Java 8 (so JavaFX is in the classpath, always):
apply plugin: 'groovy'
compileJava {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
...
It also has a test dependency on Groovy:
testCompile group: 'org.codehaus.groovy', name: 'groovy-all', version: '2.4.4'
Everything works fine, except when I refer to some JavaFX class in the Groovy test.
It fails with this error:
MyTest.groovy: 3: unable to resolve class javafx.scene.paint.Color
# line 3, column 1.
import javafx.scene.paint.Color
^
The Java code compiles fine and I can run my JavaFX application. Only the Groovy tests seem to not be able to see JavaFX.
I've already tried changing the compileJava block to compileGroovy, compileTestGroovy, also together with the compileJava block, so that the Groovy compiler sees JavaFX 8, but nothing helped.
How can I fix this?

Changed the Gradle version to 2.7 (latest as of today) and it all works.
If you have the same problem, just use Gradle's wrapper and set the Gradle version to the latest version (they move fast, so bugs will exist, but also get fixed quickly).
gradle wrapper --gradle-version 2.7
I am running gradle and have previously been running groovy 1.76. I have now updated to groovy on my local machine (groovy_home points to groovy 2.1.2 etc).
$ groovy -version
Groovy Version: 2.1.2 JVM: 1.7.0_17 Vendor: Oracle Corporation OS: Linux
However, when I am running gradle commands (gradle test, classes, etc) I believe it is not building against groovy 2.1.2 but is actually still building against 1.76. (The reason I believe this, is that when I execute the classes I keep getting this error Upgrading Groovy 1.7 - 2.1 Incompatability, which is related to changes made post 1.76)
Is there a way to confirm which version of groovy my gradle install is building against?
Also, can anyone confirm where I should be configuring the groovy version for gradle?
While trying to check the groovy version during gradle runtime, I found you can also print the Groovy version:
task version {
doLast {
println "Gradle version: " + project.getGradle().getGradleVersion()
println "Groovy version: " + GroovySystem.getVersion()
}
}
As examples:
$ ~/usr/gradle-1.8/bin/gradle -q version
Gradle version: 1.8
Groovy version: 1.8.6
$ ~/usr/gradle-2.1/bin/gradle -q version
Gradle version: 2.1
Groovy version: 2.3.6
Note.- GroovySystem.getVersion() is available since Groovy 1.6.9
Which Groovy library you are building against (and which Groovy compiler you are using) is determined by which Groovy library resides on the compile (or, in earlier Gradle versions, groovy) configuration. Typically a Groovy dependency is configured explicitly, but it may also be pulled in by transitive dependency management. (In case of a version conflict, the higher version wins by default. Which Groovy version(s) you have installed on your machine is irrelevant.) gradle dependencyInsight --configuration compile --dependency groovy should provide the answer.
Here is how a Groovy dependency is typically configured:
apply plugin: "groovy"
repositories {
mavenCentral() // or some other repository containing a Groovy library
}
dependencies {
// in Gradle 1.4 or earlier, replace 'compile' with 'groovy'
compile "org.codehaus.groovy:groovy-all:2.1.2"
}
in windows you can check it using: gradlew --v
