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.
This gives the WALA maintainers the option of doing future 1.4.5+
releases from of a pre-Gradle branch if these merged Gradle changes
turn out to be more disruptive than expected.
Previously Buildship removed its classpath from all of these
launchers. Now it's automatically putting that back in as soon as I
visit each launcher in Eclipse's "Run Configurations" dialog. Not
sure what's going on here, but it certainly seems more sane to me to
assume that the Buildship-computed classpath *is* needed for all of
these. I have an open question on the Gradle discussion forum to try
to understand what's going on here and how to fix it:
<https://discuss.gradle.org/t/launchers-lose-buildship-classpath-on-import-regain-it-later/25641>.
This consistently happens when I import WALA as an existing Gradle
project into Eclipse with Buildship. I don't really know what this
change means, or whether it's desirable. For now, I'm going to trust
Buildship and see what happens.
These settings files currently are generated with an initial timestamp
comment line, which is not something we'd want to track in version
control. Fortunately, the contents of these files are entirely
mundane, so there should be no problem with having Buildship generate
them anew each time a developer imports WALA into Eclipse as an
existing Gradle project.
Apparently Buildship generates these when one uses Import -> Existing
Gradle Project:
<https://discuss.gradle.org/t/buildship-eclipse-plug-in-multiproject-builds/24030/5>.
We can use the Gradle "eclipse" plugin if customizations are
necessary, but my impression is that the intent is to treat ".project"
and ".classpath" as generated files, not sources to be tracked in
source control.
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).

Eclipse's automated code clean-up tool did most of the heavy lifting
here: it specifically has a clean-up option for converting functional
interfaces to lambdas. I merely had to revert the automated changes
for a single enumeration class for which it produced invalid results,
and for a few test inputs that apparently aren't set up to be compiled
with Java 8.
These are all problems that Eclipse can detect, but that it detects no
instances of right now. Treating these as warnings instead of errors
should help prevent us from slipping backward in the future.
