I created scala application and now I want to build jar.
I run mvn package than I try to run jar by command
java -jar target/burner-1.0-SNAPSHOT.jar
and I see error:
Failed to load Main-Class manifest attribute from
How can I define Main-Class property? Do I need to create Manifest.mf? where? Or I need to have mainclass property somewhere in pom.xml?
Update: I have created src/main/resources/MANIFEST.MF file with contents
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: itsabear
Main-Class: ru.dmteam.App
Build-Jdk: 1.6.0_20
I did not forget line ending at the end of file.
after mvn package I see new jar. I checked manifest.mf in this jar - it contains right main-class but when I type java -jar target/burner-1.0-SNAPSHOT.jar I still see an error Failed to load Main-Class manifest attribute from
My pom.xml http://pastie.org/1070483
UPDATE 2
I discovered that now there are two manifest.mf files in the jar.
MANIFEST.MF and META-INF/MANIFEST.MF
I moved my custom MANIFEST.MF to just created META-INF folder(in src/main/resources) but now mvn package overrides it while creating jar...
