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.
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).
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.
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.

Julian Dolby assures me that WALA is now supposed to be using Java 8
everywhere. This covers nearly all remaining places that I can find
where an earlier Java version was still being used. (The few
exceptions are places where switching to Java 8 causes test failures.
I'll address those separately, probably by reaching out to the WALA
maintainers for help.)
This fixes two Eclipse Plug-in Development warnings of the form "Key
'...' is not found in localization properties file:
OSGI-INF/l10n/bundle.properties".
The single "No grammar constraints (DTD or XML Schema) referenced in
the document" warning arises in a generated file. I doubt that we can
change the generation process to include grammar information. Even if
we could, I don't mind omitting validation here assuming that we can
trust the generator tool to be correct. Validation is much more
important for human-authored XML; for tool-authored XML, we can live
without it.
When Maven generates these "*/target/antrun/build-main.xml" Any build
scripts, it does not include any DTD or XML Schema declarations.
Eclipse's XML validator warns about the lack of grammar constraints.
The warning is sensible, but we are not in a position to do anything
about it. Better, therefore, to suppress these warnings so that we
can more-clearly see warnings we *can* address.
I think the "target/p2artifacts.xml" and "target/p2content.xml" files
are generated by Maven. They are well-formed XML but Eclipse's XML
validator legitimately warns that they lack grammar constraints.
Since we're not maintaining the tool that creates these files, we are
not in a position to do anything about that. Therefore, we may as
well exclude these from validation entirely. That way we can
more-clearly recognize warnings that we *can* do something about.
Ant "build.xml" files don't have a standard DTD or XML Schema; the
contents are simply too flexible for that. But we can at least
give each a stub DOCTYPE declaration. That's enough to satisfy
Eclipse's XML validator, which otherwise complains that these files
lack grammar constraints.
It's unclear whether the original authors of these pages intended them
to be valid or invalid. Certainly there is merit in testing against
invalid HTML, since the vast majority of real-world HTML is indeed
invalid. I'm going to assume that any errors in this collection of
test inputs are intentional, and therefore not worth reporting when
running Eclipse HTML validation.
