Maven从Eclipse而不是命令行中看到依赖的项目jar

Question

I'm having trouble building my maven project outside of Eclipse. In eclipse, I am able to do it without issues and all dependencies are resolved.

The error I get is that it cannot find the jar file from the dependant project:

    myuser@Laptop:~/workspace/Measurement_processor$ mvn clean -X compile

The ultimate goal is to get this to work on jenkins, but the first step is to get it to run on terminal.

UPDATE:

I cleaned up (deleted) directories with compiled sources in the repository for mydomain and then reran the install for the CommonLibraries. That worked!

I got errors after that, but they were related to me having test classes dependent on TestNG in the main folder. It now works.

Answer 1

Run "mvn clean install" for the project responsible for the com.mydomain:CommonLibraries:jar:0.0.1-SNAPSHOT artifact so it gets created in the Maven repository.

The behavior you see is because m2e can resolve artifacts from Eclipse projects directly.
