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.
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 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.
These are all things one might consider fixing in real application
data. Java code used as test inputs, though, serves a different
purpose. Weird code is generally acceptable or even intentional.
Previously we had 227 such warnings. That large number suggests that
the WALA developers consider this to be an acceptable coding style.
If that's so, then it's better to hide these warnings rather than keep
them around as a perpetual distraction.

I have *not* upgraded this problem to be treated as an error in the
future. Unfortunately Eclipse uses a single configuration setting for
both unnecessary semicolons and also for empty control-flow statements
like `while (p) ;`. I'm not convinced that it's worth rewriting all
instances of the latter into `while (p) { }`. So this is just going
to stay as a warning for now.
The fix is to add "static" where appropriate, of course. I've also
simplified calls to such methods to reflect the fact that they no
longer need a specific object to call the method on.
In projects that contain test inputs, I've left the non-static
declarations unchanged, and instead downgraded the warning to be
ignored. In all other projects, this warning has been upgraded to an
error.
Along the way, I also converted many "for (;;)" loops into modern
"for (:)" loops. I didn't systematically look for all opportunities
to do this, though. I merely made this change where I was already
converting raw Iterator uses into modern Iterator<...> uses.
Better use of generics also allowed many casts to become statically
redundant. I have removed all such redundant casts.
Only three raw-types warnings remain after this batch of fixes. All
three involve raw uses of CallGraphBuilder. I've tried to fix these
too, but it quickly snowballs into a cascade of changes that may or
may not eventually reach a statically-type-save fixed point. I may
give these last few problem areas another go in the future. For now,
though, the hundreds of other fixes seem worth keeping even if there
are a few stragglers.
This commit may change some public APIs, but only by making weaker
type signatures stronger by replacing raw types with generic types.
For example, we may change something like "Set" into "Set<String>",
but we're not adding new arguments, changing any
underlying (post-generics-erasure) types, etc.
Apparently this code is built using Java 1.6 under Tycho. This leads
to complaints about the Java 1.7+ "<>" generic type inference feature,
if I try to use it. Weirdly, the Eclipse GUI does not complain about
this, so apparently the Eclipse GUI is using Java 1.7 or later. I do
not understand why Tycho and the Eclipse GUI are mismatched in this
way.
There are two such diagnostics: one for collection methods and one for
equals(). See
<https://www.eclipse.org/eclipse/news/4.7/jdt.php#unlikely-argument-types>
for more information about these two new diagnostics.
For each of these diagnostics, I've set the severity level to
"warning" in projects that have some instances of the suspicious code,
or to "error" in projects that have no instances of the suspicious
code.
In general, test code may do all sorts of things that would be
considered poor style in production code. I assume that these
potentially-static methods are declared non-static by design.
These should mostly be things that we've already decided earlier that
we explicitly don't want to "fix" because they simply disagree with
the WALA project's coding style.
The additional diagnostics are ones that were previously being
ignored, but which we seem to have been ignoring by default rather
than as a conscious choice.
For diagnostics of which we currently have *zero* instances, treat
these as errors rather than merely warnings. The intent is to
permanently lock out future regressions of things we've completely
fixed. In the future, whenever we fix the last instance of a given
warning in a given Eclipse project, we should also promote that
diagnostic to an error to keep things clean into the future.
Often the easiest way to create a desired test scenario is to write
code that would make no sense in a complete, realistic application.
So we generally want to let test code do oddball things.
