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 should prepare test resources for all subprojects. A WALA
developer should run this once before running any tests inside
Eclipse. Initially I'd hoped to make this more narrowly focused, but
Eclipse just doesn't have the infrastructure to deal with fine-grained
dependencies. On the other hand, running "./gradlew
eclipsePrepareTestResources" automatically for each build seems like
overkill, and could end up being rather slow. So for now we require
that the developer run this once, by hand.
A cleaned tree is now much closer to a pristine tree that has just
been checked out and never built. The only extra created files that
are left behind are ".gradle", "buildSrc/.gradle", and
"buildSrc/build".
This gets rid of some Eclipse warnings that stem from Buildship being
confused about what it should treat as a source directory if Maven and
Gradle are both being used in the same tree.
Previously we were repeating the library path twice, but that's not
good for long-term maintenance. That being said, extracting this
information from the depths of the native software model seems *far*
more complex than it should be. I had hoped for something nicer in
response to
<https://discuss.gradle.org/t/compute-wl-rpath-flag-suitable-for-native-shared-library/25278>,
but so far there's nothing.
Previously Maven did this, but Gradle did not. So Gradle testing
would only succeed if we'd already done a Maven build first. Now
these tests pass in a fresh tree that's never seen a Maven build.
Some tests in other subprojects do depend on some these extra jar
files. But they can declare those specific dependencies as needed.
Nothing seems to depend on the entire group of extra jars, so it's not
really useful to declare a task that is merely an alias for all of
them.
Many tests are excluded until
<https://github.com/liblit/WALA/issues/5> is fixed. But we can at
least have Travis-CI watching over our shoulder to ensure that
no *new* regressions sneak into the tree.
<https://github.com/liblit/WALA/issues/5> notes that several
subprojects' tests are currently broken under Gradle. I'd still like
to be able to run non-broken tests, though. So here I'm disabling the
failing tests. The intent is to treat these exclusions as a to-do
list. We can remove exclusions as we get the corresponding tests
working. No more exclusions means
<https://github.com/liblit/WALA/issues/5> is fixed.
It's rather slow, adding roughly five seconds to every "./gradlew"
invocation. And the advice it gives might not even be reaching a
fixed point. I like the idea of running the linter as part of CI
testing, but I now think it's overkill to impose on every developer
build.
