When IntelliJ IDEA imports WALA's Gradle configuration, it creates
what is calls a "module" for each sourceSet of each Gradle subproject.
In so doing, it automatically picks up the source and resource
directories used by each of these sourceSets. Unfortunately, IntelliJ
IDEA does not allow multiple modules to share a single root directory
as their source or resource directories, and that's exactly what was
going on with the "example-src" subdirectory under
"com.ibm.wala.cast.js.test.data".
This revised Gradle configuration still has is copying the necessary
"example-src" resources to the appropriate locations for use as test
resources. But IntelliJ IDEA no longer treats "example-src" as a root
directory for resources in the automatically-generated modules. So
now we get along nicer with IntelliJ IDEA while keeping everything
working with Gradle as well.
WALA itself does not use any JUnit 4.12 features. However, I am
working on a WALA-based project that does require JUnit 4.12. Mixing
jar versions is a path to madness. So if the WALA maintainers don't
mind, it would make my life easier if WALA itself required JUnit 4.12.
Otherwise, I need to maintain that 4.11/4.12 difference indefinitely
as a divergence between official WALA and my WALA variant.
I suppose an alternative could be to let the JUnit version be
specified externally somehow. I have not explored this option in
depth, but could look into it if simply moving to JUnit 4.12 is
undesirable.
I was confused about the differences among:
srcDir 'foo'
srcDirs ['foo']
srcDirs = ['foo']
As it turns out, the first two append to the set of source
directories, while the last replaces this set entirely. I generally
want replacement, since WALA's current directory layout never matches
Gradle's assumed defaults.
The main requirement here is to arrange for the proper classpath
settings when tests are running so that they can find any associated
resources (i.e., other supporting files).
