Re: [tycho-user] Empty Boot Classpath Using Toolchains + Java 7 on OS X?
|
There is a bug in the way Tycho detects jdt installation layout on OSX
(please open a bug report). You should be able to workaround it by
providing explicit includes/excludes patters in toolchain configuration
as explained in
http://eclipse.org/tycho/sitedocs/tycho-compiler-plugin/compile-mojo.html#useJDK

Hello all,
Has anyone had problems building Eclipse plugins with Oracle Java 7
(1.7.0_51) via Toolchains on OS X (10.9)? I'm getting some very strange
compilation messages, which seem to imply that the base rt.jar classes
can't be found. Building with Eclipse/PDT doesn't seem to have issues,
but command line mvn or Eclipse M2E fails with the following:

I believe the toolchains.xml entry is correct (I've tried including the
jre subdirectory in the jdkHome path - but there seemed to be no change
in behavior):
<?xmlversion=/"1.0"/encoding=/"UTF-8"/?>
<toolchains>
<toolchain>
<type>jdk</type>
<provides>
<version>1.7</version>
<id>JavaSE-1.7</id>
</provides>
<configuration>
<jdkHome>/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home</jdkHome>
</configuration>
</toolchain>
</toolchains>
The Maven debug output looks mostly reasonable - except for the Boot
classpath entry near the end, which I would normally think should have
the rt.jar reference:

My sample project (which I think is a fairly basic Eclipse/PDT/Tycho setup)
Other notes:
- Switching back to Tycho 0.19.0 doesn't change the behavior
- Using Apple's JDK 6 previously for a JavaSE-1.6 profile didn't have
these problems, but I'm trying to update myself to a pure Java 7 setup
Anyone seen something like this before? I somewhat expect that I'm
missing a magic flag in my toolchains.xml, but I haven't yet been able
to find it after digging through the source code.
Thanks in advance for any pointers you can provide,
--Jim
