Failed to find Premain-Class manifest attribute in …\PushServer\target\Push-Server-0.12.0-capsule-fat.jar

问题

I follow the guide to running signal server at this link:

https://github.com/lucaconte/BeatTheMeddler

When i try to run the PushServer at this step:

java -jar Push-Server-<VERSION>-capsule-fat.jar server YourPushServerConfigFile.yml

Then an error raised:

Failed to find Premain-Class manifest attribute in ...\PushServer\target\Push-Server-0.12.0-capsule-fat.jar Error occurred during initialization of VM agent library failed to init: instrument CAPSULE: Client connection failed. CAPSULE EXCEPTION: Accept timed out while processing null null: null (for stack trace, run with -Dcapsule.log=verbose)

I've been create manifest with this two scripts and also point main class to PushServer.java in netbeans, but the problem persist.

jar -tf Push-Server-0.12.0-capsule-fat.jar

jar -xf Push-Server-0.12.0-capsule-fat.jar META-INF/MANIFEST.MF

Anyone know what the issue is?

回答1:

ok, this is the capsule issue

in pom.xml change the version to newer, in my case 1.0.1

<!-- <capsule.maven.plugin.version>0.10.0</capsule.maven.plugin.version>-->
     <capsule.maven.plugin.version>1.0.1</capsule.maven.plugin.version>
