第谷詹金斯构建失败-nullpointer

Question

I have problems with Tycho build on Jenkins. On my local machine i have success build.

I have two projects p2 and apll. In p2 I simply repack artifacts to eclipse-plugins with well formated manifest, pom etc. This build is ok.

Apll build fails when is about to start compiling plug-ins. When I point Jenkins directly on my plugin pom, I have success build. But when I start from parent pom it fails. My project structure:

-root
  |-core
    |-plugin1
    |-plugin1junit
    |-plugin2
    |-plugin2junit
    |-core-feature
  |-lib-feature
    |-nattable-feature
    |-chart-feature
  |-product

root - pom with tycho plugin and target platform conf, dependencys to p2 plugin //package pom

core pom

lib-feature - features from p2 plugins

product - materialization

build result:
root - SUCCESS 
Core - SUCCESS
p2-feature - SUCCESS
nattable-feature - SUCCESS
chart-feature - SUCCESS
plugin1 - FAILURE 
... - FAILURE 

and stack:

Answer 1

Jenkins中的Maven作业类型一直在提供NPE，但这已在Jenkins的最新更新中得到解决，因此请尝试更新您的Jenkins以查看是否可以解决。

Answer 2

This looks like a bug in Tycho 0.14.0-SNAPSHOT that was fixed a while ago already. Are you by any chance still using an outdated Tycho 0.14.0-SNAPSHOT version?

Neither Tycho 0.13.0 nor Tycho 0.14.1 should have this problem.
