Thanks a lot @danglotb

FYI SOS not fixed GradleAutomaticBuilderWithDescartesTest.setUp:56 » Runtime java.io.IOException...

See https://ci.inria.fr/sos/job/dspot/148/console

WDYT?

Thank you for the info.

It looks like gradle is not installed on the node:

java.lang.RuntimeException: java.io.IOException: Cannot run program "gradle" (in directory "/builds/workspace/dspot/dspot/src/test/resources/test-projects"): error=2, No such file or directory
	at java.lang.UNIXProcess.forkAndExec(Native Method)
	at java.lang.UNIXProcess.<init>(UNIXProcess.java:247)
	at java.lang.ProcessImpl.start(ProcessImpl.java:134)
	at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029)

	at eu.stamp_project.dspot.common.automaticbuilder.gradle.GradleAutomaticBuilderWithDescartesTest.setUp(GradleAutomaticBuilderWithDescartesTest.java:56)

I see three ways to get out of this:

1. @Ignore the tests of GradleAutomaticBuilder
2. Try to install gradle on the node
3. Find another way to fix the original issue.

I prefer the first option because this feature is not the core of DSpot and a bit in extra. I would love to remove it from DSpot. WDYT?

OK for me to @ignore the tests of GradleAutomaticBuilder. Would you do a PR? Thanks!
