Hi,
I need to use a java instrumentation agent in my JUnit 4 tests to enable
Spring load-time weaving.
So far, I've tried to declare the agent library as an external dependency,
and then refer explicitly to the cache path in the test task:
test {
options.fork(jvmArgs:
["-javaagent:"+System.getProperty('user.home')+"/.gradle/cache/org.springframework/spring-agent/jars/spring-agent-2.5.6.jar"])
}
Is there a better way to get the dependency path in the cache ? for instance
can we get a File object from a resolved external dependency ?
You can get them as a Set:
Set<File> agentFiles = configurations.runtime.files { it.name ==
'spring-agent' }
I think I would use a custom configuration for this:
configurations {
springAgent
}
dependencies {
springAgent name: 'spring-agent', version: ...
}
test {
options.fork(jvmArgs:
["-javaagent:$configurations.springAgent.singleFile"])
}
There's a few more options for getting the files for a dependency. Have
a look at the Javadoc for Configuration:
http://gradle.org/0.7/docs/javadoc/org/gradle/api/artifacts/Configuration.html
In this case, does it make sense to declare the dependency in the "runtime"
configuration or would it be better to use a custom configuration ?
Or would you advise me to not use a dependency but instead commit the agent
in the project directory in the VCS ?
I'm very new to Gradle and totally unexperienced in Groovy, please share
your experience ! ;)
Thanks,
Romain.
