Agent failed to start #44
Description
At first, when I tried to run my .jar which uses the ea async dependency, I got the error that it couldn't find the class agend in my manifest. Therefore, I added
Agent-Class: com.ea.async.instrumentation.Agent
to my MANIFEST.MF and it seemed to fix this error, but now I got a new one and I really don't know what I am doing wrong.
It's a maven project so that's what I did:
- Added the dependency to my pom.xml
- Added the plugin to my pom.xml
- I rebuild the project, recreated the artifacts to apply possibly missing changes.
- I started using it with the import parameter
import static com.ea.async.Async.await;like on the examples.
It works fine if I start it in my IDE (Intellij / Javac 11), but does not if I put the compiled .jar (which contains the com.ea.async dir) on my debian 9 server and try to launch it there (it runs with open jdk 11).
I am grateful for any help! 🙏
This is my error (Servant is the name of my program):
