I writing gradle plugin for code generation, and it's use groovy org.codehaus.groovy.runtime.ExtensionModule.
But extensions resolve on gradle (daemon) start stage, and add jar with META-INF/services/org.codehaus.groovy.runtime.ExtensionModule into build script classpath has no effect.
How to register ExtentionModule manually?
I don't believe you can, as it says in the documentation:
to use an extension, it has to be available on classpath, as compiled classes, before the code using it gets compiled

Can jrebel detect a jar file has been added to maven/gradle and then automatically add it my libs folder and add it to the classpath?
For example I'm running IntelliJ and Jetty and I make a gradle change to add a new version of a jar dependency and then click "gradle refresh."
Can jrebel be set up to load that jar? Otherwise this requires a full restart which partially makes jrebel less useful.
The short answer is no.
JRebel works by reloading individual class files, but not whole JARs.
If you add a new dependency or update the version of an existing dependency then it won't get reloaded.
However, if this library you're updating or adding is your own internal library that you build yourself, then it is possible to reload the changes.
In that case you need to build a rebel.xml file into the root of that library jar and configure it to point to the build directory of the library.
I have a Java project that has a lot of unit tests written in Groovy.I do not have the GDK installed and it still runs.
The project uses gradle and it has "apply plugin: groovy" in the build script but I was under the impression that it would just use groovyc which is definitely not installed.
How does this work?
Thanks
Inside your build.gradle file, inside the dependencies block, you will have a line probably like:
compile 'org.codehaus.groovy:groovy-all:2.4.1'
This line pulls in the specified version of groovy, and the groovy plugin uses it to compile your groovy code
Assuming all my Gradle plugin user going to have a MYAPP_HOME sys variable set in there system
in MYAPP_HOME page i have a jar at $MYAPP_HOME/lib/mylib.jar
i am writing my own plugin....
I can find the MYAPP_HOME variable is set and fine the jar exists..
How can i add this jar dependency in my custom gradle plugin... ? when user runs my plugin say compileMyplugin my custom gradle plugin need to set the $MYAPP_HOME/lib/mylib.jar jar as compiler dependent
How to do this any one help me ?
The plugin just needs to do:
project.dependencies {
compile project.files("${System.getenv("MYAPP_HOME")}/lib/mylib.jar"))
}
PS: In general, I wouldn't recommend relying on an environment variable and the availability of a Jar on the local file system. Instead, I'd publish the Jar to an artifact repository or put it under source control.
we have a project where we use Maven to deploy to Tomcat on mvn clean install. I'm fairly new to Java development and finding it difficult to continually wait for install to complete to view changes. I use IntelliJ and I think the class files are only created during mvn install in the target directory.
Is it possible to use JRebel so when I save a file in IntelliJ the compiled class updates Tomcat immediately like they show on the JRebel video?
Thanks
IntelliJ saves the file automatically for you. All you need to do is to recompile the changed classes and these will be picked up by JRebel, given you have included rebel.xml configuration file into the deployed archive.
I try to run my first Spock Test inside Eclipse, and it does not work.
I added all the Maven dependencies and plugins in my pom.xml, but when I run my test with jUnit, there is a popup windows with this Warning message : "No jUnit tests found".
Did you already seen this kind of message ?
What config has to be done, in order to run a Spock Test inside Eclipse ?
Thanks a lot.
Its same as running Junit test cases.
Right click on the class and run as 4Junit Test runner. see below for complete configurations and running the spock test.
Running Spock Framework with Eclipse, Gradle, Groovy: Source -
Krzysztof Goralski, blog
-Install Gradle Plugin, check it here
-Install Groovy-Eclipse for Juno or Indigo from Eclipse Marketplace (or maybe Groovy/Grails Tool Suite for Eclipse)
-Install Spock Plugin From Eclipse Marketplace if you want, check it here
-Import Project to Eclipse through Gradle Import
-Add these lines to build.gradle:
apply plugin: ‘groovy’
testCompile ‘org.spockframework:spock-spring:1.0-groovy-2.3’ (for Spring)
this is quite important, version can make some conflicts
-After this *.groovy and *.gradle files will problably looks different, Syntax colour highlightning etc. Remember that you can right click on for eg. build.gradle -> Open with -> Open With Minimalist gradle Editor etc.
-Probably you will need to make additional folder for *.groovy test files
Create new *.groovy file, class
-Basic test example, extends Specification from Spock framework and needs specific Annotations when running with Spring
-Now you can run it with JUnit from Eclipse
For integration tests you can’t use #RunWith(SpringJUnit4ClassRunner.class), and Context should looks like here #ContextConfiguration(locations = [ “/restTestContext.xml” ]) , not {} braces, but [ ]
-Spock can be used for Mocks too. Something like this: Subscriber subscriber1 = Mock() , subscriber1.isActive() >> true , So, remember >> operator for mocks.
Right click on the project > Properties > Java Build Bath > Add External Jars and add spock-core-0.6-groovy-1.8.jar and check if Groovy Libraries are there in Build Path or not. If not click on Add Library and select Groovy Runtime Libraries and restart Eclipse. Now you should be able to run. If still can't Run then try creating New Configuration and change the Test runner to Junit4 and Run it...
Check if the folder your tests are in is a source folder.
