如何配置Maven以使用本地工件

Question

I'm trying to modify an existing project X and to test it there is another project Y that use the X project's jar (I know it is not the best way to do tests, but there is some constraints)
My question is : how to configure maven to use the local version of the project X jar (there is other version of X jar ) ? I tried to change the dependency version but it doesn't work, I also disable update of local repo and run mvn command offline, but none of these are working .

Answer 1

Build project X locally with a different version (like 1.2.3-TEST-SNAPSHOT ) and reference this version in project Y.

If the projects are both Eclipse projects, you can also use Eclipse workspace resolution to directly resolve against the other project (inside Eclipse).

Answer 2

Ok, The first, You must build project X, choose maven build or run mvn clean install. Then after success, you can check in folder m2/repository///bla bla. You can see file X.jar In file pom of project Y, you add dependency of project X. GroupID and ArtifactID of project X you can see in file pom of project X.

Answer 3

1. Build your project X and then
2. Build project Y in offline mode using option o, something like this: mvn -o clean install -O option will not download X's version from the remote repository. It will use $M2_HOME version of X on your local repository which was installed by your build.
