Classname glue causes crash

[Steve Ramage]

When using the IntelliJ Cucumber plugin, when I try and right click on any feature file I get a crash:

Exception in thread "main" java.lang.IllegalArgumentException: Not a file or directory: /home/myname/git/com.mydomain.foo at cucumber.runtime.io.FileResourceIterator$FileIterator.<init>(FileResourceIterator.java:63)
    at cucumber.runtime.io.FileResourceIterator.<init>(FileResourceIterator.java:28)

It seems that the command line that is being generated includes.

/usr/lib/jvm/java-8-jdk/bin/java <ARGS>  -classpath <CP> cucumber.api.cli.Main --plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm2SMFormatter --monochrome --glue com.elasticpath.fixtures --glue com.mydomain.foo /path/to/somefeaturefile.feature

@mpkorstanje helped me out and pointed out to this code where he suspects their may be a problem:
https://github.com/cucumber/cucumber-jvm-groovy/blob/master/groovy/src/main/java/cucumber/runtime/groovy/GroovyBackend.java#L82

In particular that it might need to be prefixing classpath. But I do notice that if I just force the glue on my run configuration in IntelliJ to be classpath:com.mydomain.foo the problem goes away, so I wonder if it's a problem with that.

Hi @SJrX ,

All you've described is correct.

Package names should be prefixed with classpath in glue path.

This prefix is used to determine which resource loader to use https://github.com/cucumber/cucumber-jvm/blob/e471442b0bd6a6d263bbcac03c8079107a36d84d/core/src/main/java/cucumber/runtime/io/MultiLoader.java#L18

If no classpath prefix specified, this glue is treated as file/directory path and will fail with IllegalArgumentException

@glib-briia , should I open a bug with IntelliJ then. I should also point out that @mpkorstanje felt that the classpath rules were only applicable to feature files and not to glue (if memory serves).

[Glib Briia]

Yes, that is correct for java. For groovy, however, we are loading raw . groovy scripts alongside compiled ones. Let me take a look how we can handle that gracefully

[M.P. Korstanje]

Is it common for raw groovy scripts not to be on be placed the classpath?
