The default location of DroidBench in "/tmp/DroidBench" does not work
well on Windows. So let's disable these tests until someone has time to
make that path more portable.
This URL skips over a redirect that the previous URL went through.
This URL also avoids an annoying "Invalid cookie header" warning that
the previous URL produced.
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.
I believe Travis CI jobs get two CPUs by default.
Doing parallel builds regularly is also a good way to help us discover
any build race conditions we may have. There's no guarantee that any
such races will be revealed, but even exposing them
nondeterministically is better than having no possibility of exposing
them at all.
We used to use these to find various Eclipse packages, but that was
always a dodgy affair since we never quite knew whether we had
matching versions of everything. Now that we are using the
"com.diffplug.gradle.p2.asmaven" plug-in, though, we have much better
control over getting exactly the Eclipse material we need. These two
Maven repositories no longer provide anything we use, and therefore
can be removed.
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>.
Unlike Linux, macOS has no "RPATH" facility for embedding additional
search paths within shared libraries. Instead, we need to set
"DYLD_LIBRARY_PATH" appropriately in the environment. This
environment variable is the macOS analogue of "LD_LIBRARY_PATH" on
Linux.
Note that adding the required path to the "java.library.path" system
property will *not* work. This property only affects where the JVM
looks for shared objects that it is loading directly. This property
does not influence the search for other, transitively-required shared
objects.
Fixes#3.
This fixes the last of our Javadoc warnings without creating a
circular dependency between ":com.ibm.wala.cast:javadoc" and
":com.ibm.wala.cast.js:javadoc". Fixes#4, wherein more details about
this tricky dependency challenge can be found.
This lets the "DynamicCallGraphTest" tests pass. The tests in that
class expect to find some element of the classpath that includes the
substring "com.ibm.wala.core.testdata". They then treat that as a
collection of bytecode files to instrument.
Big thanks to Julian for showing me where this exclusion logic lives
in the Maven configuration. There's a "**/*AndroidLibs*.java"
exclusion pattern in the top-level "pom.xml".
It's telling me to remove "eclipse-deps:org.eclipse.core.runtime:+"
and "org.osgi:org.osgi.core:4.2.0" as unused dependencies in the
"com.ibm.wala.cast.java.ecj" subproject. However, these two
dependencies (jar files) are actually needed; compilation fails
without them.
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.
We're not going to attempt macOS Travis CI testing for Maven builds,
because I don't know whether that's even expected to work on the
official WALA master branch. Our main focus here is Gradle.
Note that Travis macOS images do not support JDK switching, so
explicitly selecting the JDK version now becomes part of the
Linux-only configuration.
Travis macOS images also do not support Android as a build "language".
So our Travis CI configuration for Gradle builds now declares that
this is a Java project rather than an Android one. That's OK, though,
because our Gradle scripts already handle downloading the Android SDK;
we don't need Travis CI to do that for us. When building using Maven,
though, we still call this an Android project because Maven builds do
still rely on Travis CI to provide the Android SDK.
squash! Enable macOS (a.k.a. OS X) Travis CI testing for Gradle builds
If future DroidBench changes include things we need, then we can
decide to move to those newer revisions. But we shouldn't allow
DroidBench to change out from under us implicitly whenever someone
commits something new to the DroidBench repository.
