Re: [platform-releng-dev] Problems building the Eclipse platform from th

[David M Williams <david_williams@xxxxxxxxxx>]

I doubt I could tell much from the logs,
but can offer three other tips I've found important. And if these dont'
solve the problem ... I'm sure you'd be over my head. 

A. Make sure your source tree is not
just clean, but pristine. See http://wiki.eclipse.org/Platform-releng/Platform_Build#Cleaning_the_build_repo
B. Delete your "local maven repo"
to be sure it has only the freshest, most current stuff in it. 
C. Don't recall right off if it was
Juno or Kepler, but at one point we had a bundle that specified "1.3"
in the BREE, which is not covered by the EE libraries, and in fact its
impossible to find a 64 bit version of Java at 1.3 level. But, what I found
was that Tycho is perfectly happy with a 32 bit version in the toolchain
file, as all it does is use its libraries on the classpath. Doesn't check
if it is "runnable" or not. 

If those don't help, you might have
better luck asking on "cbi-dev" list (Eclipse CBI <cbi-dev@xxxxxxxxxxx>)
as this list (platform-releng-dev) is more concerned with our "production
builds". 

Good luck,

Hi David,
 
Thanks for taking the
time to reply,
 
> I assume you really
do have your toolchains file at ~/.
 
Well, sort of, the file
comes from inside a repository which contains things required for our release
process so it will be somewhere that is always available but not in the
default location. That was what I was trying to get across with my sample
build command, sorry for muddying the waters.
 
I tried specifying -Pbree-libs
on the mvn command line and initially the build failed because I wasn’t
specifying an OSGi/Minimum-1.2 in the toolchain.xml. I’ve downloaded the
ee.zip from the build instructions and updated my toolchain.xml so it has
all the sections of the sample one from that page and the build still fails
with this message:
 
[ERROR] Failed to execute
goal org.eclipse.tycho:tycho-packaging-plugin:0.19.0:package-feature (default-package-feature)
on project org.eclipse.e4.rcp: Execution default-package-feature of goal
org.eclipse.tycho:tycho-packaging-plugin:0.19.0:package-feature failed:
Could not determine installation size: zip file is empty -> [Help 1]
 
Whilst trying to build
org.eclipse.e4.rcp. Why is it trying to determine the installation size
when the build is only half completed?
 
For avoidance of doubt
I am now running
 
mvn -e --toolchains ~/.toolchain.xml
 -Pbree-libs clean verify
 
Would it be helpful to
attach some more of the error log (I’ve tried to cherry pick the relevant
section but I might be wrong)? Is there anything else I can supply to help
to get to the bottom of this?
 
All the best
 
Phil

I could reproduce the problem you are seeing,
following your steps, .... 
side issue: typically its under ~/.m2/ 
but no reason it has to be, if you specify on command line ... just thought
i'd mention it. 

But, if I specify -Pbree-libs on mvn command line, then it builds to completion.
In fact, I think you only need a 'toolchains' file (for our build) if you
use the bree-libs profile. 

I always run with -Pbree-libs so not sure if something changed, or if you
just forgot that part. I know at times it has worked without users having
to specify -Pbree-libs but at other times we could not avoid it. 

[If you find that fixes your issue, you might add a note in the wiki its
now required.] 

Thanks, good luck.

Hi All, 
  
I'm struggling to build the Kepler Eclipse platform from the R4_3_maintainence
branch. I used to be able to do so using the instructions from http://wiki.eclipse.org/Platform-releng/Platform_Build
 but about 1 week ago the build started to fail. My build process
is this 
  
    git clone -b master --recursive git://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.git
    cd eclipse.platform.releng.aggregator
    git checkout -b R4_3_maintenance origin/R4_3_maintenance
    git submodule update 
    export MAVEN_OPTS="-Xmx2048m -XX:MaxPermSize=512m"
    export JAVAVER=jdk1.7.0_13 
    mvn --toolchains ~/.toolchains.xml clean verify 2>&1
| tee build-output.log 
  
which I think reproduce the instructions from the above page and this method
was working for more than a month. 
  
I've checked the following 
  
+ I don't have a settings.xml file in my ~/.m2 directory
+ I have checked for pom.xml updates and I can't find any
+ My JVM is running in server mode 
+ My version of maven is later than the requirement
  
The only change I can find in the instructions relates to building from
the R4_3_1 tag but says that it shouldn't apply to the maintenance branch.
  
The error I get when building is: 
  
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.19.0:package-feature
(default-package-feature) on project org.eclipse.equinox.core.sdk: Execution

failed: Could not determine installation size: zip file is empty ->

failed: Could not determine installation size 
    at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:224)
  
Can anybody offer suggestions for what I need to do to get the build working
again? 
  
Any help that anyone can offer would be much appreciated
  
Thanks in advance 
  
Phil
