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.
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.
This task has an input named "hello_hash.ml", and an output named
"hello_hash.jar". So calling this task "generateHelloHash" is too
vague. Now we call it "generateHelloHashJar" instead.
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.
Previously this launcher's job was to run "processTestResources" and
any other Gradle tasks needed to create files that Eclipse was
expecting to be available. But we also want to use it to revert the
bad changes that Buildship applies to ".launch" configuration files.
This is a temporary hack to work around
<https://github.com/eclipse/buildship/issues/653>.
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".
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.

This fixes two Eclipse Plug-in Development warnings of the form "The
'javacProjectSettings' build entry should be set when there are
project specific compiler settings".
This removes three Eclipse Plug-in Development warnings of the form
"This plug-in does not export all of its packages"
I assume that omitting some exports is OK, because apparently nothing
else fails to build against these. If an omitted export were needed
elsewhere, something would fail to build.
