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.
If multiple tests both write to "/tmp/cg.txt" (for example), then
these tests cannot safely run concurrently. That never used to be a
problem with Maven, since our Maven tests were all strictly sequential
anyway. But parallelized testing using Gradle requires that we do
better. Fortunately, Java has perfectly reasonable APIs for
generating uniquely-named temporary files and directories.
We now download and verify checksums as a single task, rather than as
two separate tasks. This simplifies other task dependencies, since we
no longer have a checksum-verified "stamp" file separate from the
download itself. Unfortunately the combined task now has a
significant amount of repeated boilerplate. I'm hoping to refactor
that all out into a custom task class, but haven't yet figured out the
details:
<https://github.com/michel-kraemer/gradle-download-task/issues/108>.
We now also use ETags to be smarter about when a fresh download is or
is not actually needed. I think there are still opportunities for
improved caching here, but this is a step in the right direction.
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.
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.
