How to start a Maven project from command line, when using a local repository?

I have a Maven project in which I need to use a dependency that is local. To include it in the project, in pom.xml I do:

<dependency>
        <groupId>com.something.library</groupId>
        <artifactId>theId</artifactId>
        <version>1.0.0</version>
        <scope>system</scope>
        <systemPath>C:/Tests/libs/something.jar</systemPath>
</dependency>

When I build and run the project through the IntelliJ IDE, the project starts normally and runs as expected. However, when I do:

mvn compile
mvn exec:java -D"exec.mainClass"="org.example.Main"

I'm prompted with the information, that one of the classes from within that jar package, can't be found (again, that was not the case when I tried running through IDE).

Am I doing something wrong here?

Solution

  • Try installing the JAR in you local Repo. Many tutorials exist for this, e.g. baeldung.com/install-local-jar-with-maven

    TBH I have never used

            <scope>system</scope>
        <systemPath>C:/Tests/libs/something.jar</systemPath>

    Only examples I have seen are relative to the project root. Remove the C: ... perhaps it is something about jumping from one drive to another in Windows??
