WALA itself does not use any JUnit 4.12 features. However, I am
working on a WALA-based project that does require JUnit 4.12. Mixing
jar versions is a path to madness. So if the WALA maintainers don't
mind, it would make my life easier if WALA itself required JUnit 4.12.
Otherwise, I need to maintain that 4.11/4.12 difference indefinitely
as a divergence between official WALA and my WALA variant.
I suppose an alternative could be to let the JUnit version be
specified externally somehow. I have not explored this option in
depth, but could look into it if simply moving to JUnit 4.12 is
undesirable.
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 should give us a set of mutually-consistent jars rather than
picking up random, outdated pieces from Maven Central or wherever else
I could find them. We now also have a single, central place where we
set the Eclipse version that we're building against. Much, *much*
cleaner.
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>.
<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.
This partially reverts 72bc456b7. I'm starting to wonder whether the
linter might be driving us in cycles rather than reaching a fixed
point. We should keep our eyes on this.
This consistently happens when I import WALA as an existing Gradle
project into Eclipse with Buildship. I don't really know what this
change means, or whether it's desirable. For now, I'm going to trust
Buildship and see what happens.
I think these were previously not being compiled at all. Now, with
Buildship generating Eclipse ".project" settings automatically, these
are being processed. In general we don't care much about questionable
code in test data, though.
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.
Unfortunately these tests are still not finding their resources
properly at test run time. I don't know why. It seems to have
something to do with how the tests instantiate and use class loaders.
I'm probably going to need expert help with this.
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.
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).
Unfortunately the linter does not reach a fixpoint if you keep trying
to apply its suggestions. If you include "compile
'org.eclipse.core:org.eclipse.core.runtime:3.10.0.v20140318-2214'" in
the dependencies for "com.ibm.wala.ide.jdt", then the linter tells you
that this dependency is unused and can be removed. If you remove it,
then the linter tells you that it should be added. Sigh.
