Tiered compilation used to dump every stage into the same build dir, and included that dir on the classpath,
which means any ordering issues introduced into a build aren't going to result in a failed build,
thus breaking the build for everybody except those who already had a working lombok in their
build dir before starting a build. The opposite of bootstrapping, in other words.
Fixed by having each stage build into its own private stage phase.
autocleaning means that the build system detects that the usual incremental mode,
where the build artefacts are not deleted and instead used to skip steps already performed,
is not an option due to changes in the build script itself or a change in deps not detectable.
It works by having a version number which can be incremented, and a system that checks
for mismatches and forces a clean.
javac8 has a bizarre dependency situation: we need the stubs in src/stubs there to compile, but if they are there
at runtime during a test run of javac8, they take precedence over the JDK's javac (because we include this
as a separate cp entry, and thus it is not a bootclasspath item), and messes everything up.
The fix is to tell eclipse to compile various src/X folders to different 'bin' targets, which required
an update to ivyplusplus as well.
also it was just broken in general, fixed that too :)
We now test generating a level2-DOM from our level1-AST (eclipse has 3 levels of ASTs, more or less), only if
that is possible, i.e. only if the full eclipse is available. This requires using a test target named `eclipse-X`, and not
one of the `ecjX` ones. This is the change that requires the massive update to the build system. About 6 tests,
including a newly added one about @Delegate, now fail. These failures would usually not cause instant failure in
eclipse, but can cause errors during save actions and will likely mess with other things in weird ways, such as
messing up syntax highlighting.
Yes, this commit now makes a bunch of cases fail the unit tests, but that is representative of actual errors in lombok,
so I'm checking it in as is (without this commit, the problem is still there, the tests are just incapable of detecting it).
apparently on windows symlinking requires admin rights because ?????
This can be fixed with an explicit update to group policies, which I
can't assume anybody working on lombok is going to actually do.
/bin/ln in msysgit just copies (interesting choice). I could write a mechanism
that tries /bin/ln and if not there, try <copy> instead, either in the build scripts
or in ivyplusplus, but that's way too much effort to avoid a 2MB copy. So,
for now, we just copy... if more symlinking is to be done later, we'll revisit, though.
copying is such a silly waste of time, slowing down the build for no reason.
