Progress!
* Better tools[2], better scripts[3], better machine -> more packages.
* Emmanuel fixed maven/guice (#866411), and hacked ant (1.9.9-4) to fixup
the -source and -target versions. (Thanks!)
* I totally hacked up[1] maven-compiler-plugin to do the same.
Of 1261 packages compiled, 57% failed.
Of those failures:
23% think javadoc(1) doesn't exist: http://bugs.debian.org/bug=866929
I definitely think this should be fixed in the toolchain; as the
above bug.
18% still are trying to use old -source/-target:
https://paste.debian.net/974407/
Perhaps some cases ant doesn't catch it, as it doesn't look
like a Debian build environment? e.g. svnkit:
https://sources.debian.net/src/svnkit/1.8.14-1/debian/rules/#L9
https://paste.debian.net/974409/
If we can't fix enough of these in ant/maven, we might have to fix them
in javac...
11% (plus probably a lot of the above 23%) are failing doclint after
otherwise compiling successfully. doclint should be disabled,
but isn't: http://bugs.debian.org/866908
Hopefully everyone agrees we should fix this in the toolchain, as the
above bug.
7% are broken because invalid ASCII in the code is now an error;
it appears that it was only a warning on Java 8.
e.g. https://reproducible.debian.net/naga has:
[...] warning: unmappable character for encoding ASCII
... which is now:
[...] error: unmappable character (0xC3) for encoding US-ASCII
Logs: https://rbuild.fau.xxx/2017-07-02/ascii/
Maybe many of these may be fixed by defaulting the encoding,
where not specified, to UTF-8? Not toooo many to fix otherwise...
And, on a more positive note:
16% are broken due to probably intentional changes in Java 9, e.g.
* introduction of java.lang.Module
* modules changing accessiblity of things (~90 packages)
* _ becoming a keyword (~15 packages)
* apparent generics changes causing new casting problems(?)
These are in the `modules`, `keyword` and `cast` directories of the
build logs: https://rbuild.fau.xxx/2017-07-02/
6% are broken due to tests or dependencies missing. I don't know
why these are failing on my build env, but not on jenkins, and I
suggest you ignore them. They are in `deps` and `tests` in
https://rbuild.fau.xxx/2017-07-02/
This leaves just 19% of these packages (135) with random failures for
which I haven't bothered to find a classification:
https://rbuild.fau.xxx/2017-07-02/unknown/
