Groovyc and ivy

Is Ivy dependency added to the same module that uses @Grab annotation? Could you please attach a screenshot of that module's dependencies (File | Project Structure)?

There you go, attached.

Ivy seems to be there several times:

1. From alt-enter on the @grab line
2. From pom.xml
3. From the .jar that I downloaded and added.

Of course I've tried already with only one.

How many modules does your project have?

Could you please go to "File | Settings | Build, Execution, Deployment | Compiler", and add the following to the build process VM options: -Dgroovyc.reuse.compiler.classes=false
After that, please invoke compilation a couple of times. Does this help?

1. Just the one module.
2. Sorry, now I get a stack trace:

@GrabConfig(systemClassLoader = true)
@Grab('log4j:log4j:1.2.17')
@Grab('org.apache.ivy:ivy:2.4.0')

Thanks for the code sample. It might be caused by systemClassLoader parameter. Can you try compiling without it?
Another thing to try is to replace additional VM options with this: -Dgroovyc.in.process=false

hmm.  I'm not sure if this is working, but now I get the below.  The stub generation looks more than a warning.

The settings are:

1. I removed the ivy libs except for one (the jar I downloaded)
2. VM settings: -Dgroovyc.in.process=false
3. Code is

@GrabConfig(systemClassLoader =true)

@Grab('log4j:log4j:1.2.17')
@Grab('org.apache.ivy:ivy:2.4.0')

Could you please try with systemClassLoader=false?

Looks the same:

Thanks.
Is it possible for you to provide a sample project where we can reproduce the issue?

Can I email it to you directly? I've cut out parts of the current project, but I'm slightly worried that something proprietary will be accidentally left in.

Just an update for future readers of this thread.

I took my discussion with the very helpful Peter off-thread and into email.  He created a new jar to replace a plugin jar in my intellij.  Now it works!

Thanks Peter Gromov!

Paul

Thanks for the kind words!

If anyone has the same issue, attached is a jar with an experimental fix, compatible with IDEA 14.1.x. One should go to idea/plugins/Groovy/lib and replace the same-named jar with the attached one. That requires IDE restart.

The change is now present in the last 15.0.2 EAP and will be in the next 14.x bugfix release when it appears.
