[cross-project-issues-dev] 4.6M2 S-build: Download failure for org.eclip

["David M Williams" <david_williams@xxxxxxxxxx>]

Sure ... I will cross-post to cross-project
list too. 

Summary: there is an issue if anyone
is using Java 7 to build, since the Platform used Java 8 to run the build,
and to do pack200. 
See attached note for work-around for
the Java 8/pack200 issue, if you want or need to stay on Java 7 for your
builds.  

Thanks,

4.6M2 S-build: Download failure for org.eclipse.core.jobs on Hudson only

Hi David,

I noticed the same error when building Trace Compass against 4.6M2. It
took me a long time to figure out that Java 8 is required (or the jarprocessor.pack200
property) because the error message is not very clear. Would it make sense
to post this information on cross-project-issues-dev? Or maybe it was posted
already, if so I apologize for not noticing it.

Regards,
Marc-Andre

Thanks Jan, for narrowing down the issue.
We do indeed use Java 8 to build (and pack200) our Platform builds. 

Just in case others need or want to stay on Java 7, remember that there
is an VM option to specify how to handle pack.gz files. 
-Dorg.eclipse.update.jarprocessor.pack200=<location
or option>
See 
https://wiki.eclipse.org/Pack200#Pack200_Executable_location
for more details. (I'm assuming this works with Tycho, as well as install
... but, never 
tried it myself). 

Thanks again,

wget

000/plugins/org.eclipse.core.jobs_3.8.0.v20150911-1658.jar.pack.gz

unpack200 with JDK 6 or JDK 7 fails:
$ 
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/unpack2
00 org.eclipse.core.jobs_3.8.0.v20150911-1658.jar.pack.gz  test.jar
Corrupted pack file: magic/ver = CAFED00D/171.0 should be CAFED00D/150.7
OR CAFED00D/160.1



unpack200 with JDK 8 succeeds:
$ 
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin/unpack2
00 org.eclipse.core.jobs_3.8.0.v20150911-1658.jar.pack.gz  test.jar

signature of unpacked jar is verified:
$ 
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin/jarsign
er -verify test.jar
jar verified.


Any chance the build is running with JDK 7 or older (this is regardless
of
BREE setting as the maven JDK is the one in which p2 runs and does the
unpack200)?

Not sure IIRC but I had the impression p2 should fall back to plain jar
if
packed version of the artifact is not available...
