in the pom, i call it somehow like this (cannot display the xml here, is not rendered correctly on github):
mavanagaiata version 0.3.2
execution - id: load-git-branch
goal: commit

Any ideas what this might be about?

thanks!

oh, and btw thanks for updating to jgit 2.0. before that it was impossible to get a hold of jgit.

This seems to be the same bug of 0.3.2 mentioned in issue #8. Can you test the current code in master?

[nemoo]

i tried to test it but .. im doing it wrong.

i downloaded your code via zip file from github.

i changed the version in your pom to 0.3.3-SNAPSHOT

then made mvn install and copied the resulting jar to my project folder.

then i tried to reference the local dependency like that:
dependency-
groupId-com.github.koraktor /groupId
artifactId-mavanagaiata /artifactId
version-0.3.3-SNAPSHOT /version
scope-system /scope
systemPath- /myprojectdir/mavanagaiata-0.3.3-SNAPSHOT.jar /systemPath
/dependency-

then i got this error:

[WARNING] The POM for com.github.koraktor:mavanagaiata:jar:0.3.3-SNAPSHOT is missing, no dependency information available

how should i proceed?

[koraktor]

Why do you copy it (and change the dependecy scope to system)?

Remove the scope and mvn install it into your local repository.

[nemoo]

ok :)

[nemoo]

ok, did as you said and managed to get it to run in my program.

so basically you can release a new version based on the current master, that seems to fix it. so thanks for that!

[koraktor]

This is fixed in 0.3.3. It should be available from Central soon.

Hallo Sebastian,

Gibt es eine Abschätzung wann ca. die neue Version 0.4.1 auf Maven Central verfügbar sein wird?

Die Versionen dort hören bei 0.3.4 auf.

Danke!

@nemoo: Ist bereits der Fall, siehe http://search.maven.org/#artifactdetails%7Ccom.github.koraktor%7Cmavanagaiata%7C0.4.1%7Cmaven-plugin
