Maven: How to include my external jar into build executable jar

Question

I am writing Spring app and I have two external jars there. It works in IDE, but when I building the executable jar with maven it fails with error java.lang.NoClassDefFoundError: to my external jars. How can I solve this? My dependency in pom file is:

<dependency>
            <groupId>com.myapp.myappawsprovider</groupId>
            <artifactId>MyAppProvider</artifactId>
            <version>1.0.0</version>
            <scope>system</scope>
            <systemPath>/Users/Projects/Java/MyApp/MyAppProvider/target/MyAppProvider Provider-1.0.0.jar</systemPath>
        </dependency>

I build it just with men package.

If your external jars are not present in the central maven repo, you can always add them to your local maven repo with below command

mvn install:install-file -DlocalRepositoryPath=[path of local maven repo] -DcreateChecksum=true -Dpackaging=jar -Dfile=[jar file path] -DgroupId=[xxx] -DartifactId=[yyy] -Dversion=[zzz]

You can then add proper dependencies for these external jars in your pom.xml.

Hope this helps
