I don't get where you want to go: there is no disagreement on reverting
resolver from 1.4.0 to 1.3.3
the question is, once this revert has been done, about the 4 ITs failing [2]:
master #242 linux-jdk7 / Run ITs Linux Java 7
1.
org.apache.maven.it.MavenITmng0553SettingsAuthzEncryptionTest.testitEncryption
2. org.apache.maven.it.MavenITmng0553SettingsAuthzEncryptionTest.testitBasic
3. org.apache.maven.it.MavenITmng4590ImportedPomUsesSystemPropertiesTest.testit
4. org.apache.maven.it.MavenITmng4747JavaAgentUsedByPluginTest.testit
I investigated these ITs and found one common fact: they try to define
MAVEN_OPTS (and are the only ones during that)
verifier.setEnvironmentVariable( "MAVEN_OPTS", "...." );
and this does not seem to be transferred to the verifier execution
I don't know yet why this does not work on some Jenkins nodes, trying to add a
few additional output to see if I can get some hints...
any idea welcome.
Regards,
Hervé
