mvn jar文件：库包含失败

Question

I did mvn package and ran my file by doing java -jar target\\output.jar

All the jar libraries specified in the dependency of pom.xml are not included. Do advice what's wrong below. Thanks!

Below is my pom.xml to allow jar file generation.

    <plugin>
        <!-- Build an executable JAR -->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>3.1.0</version>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                        <mainClass>com.workspez.psg.letrikEtara.PlanetGroupLetrikEtara</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

Answer 1

Try and compare/complete your declaration with the ones in " Including dependencies in a jar with Maven ", like adding the executions section.

Or, if this is not working, consider the maven shade plugin , whic can achieve a simlar goal.

Answer 2

Got it working. This was missing:

<descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs>

To the following should work:

        <plugin>
            <!-- Build an executable JAR -->
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.1.0</version>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                        <mainClass>com.workspez.psg.letrikEtara.PlanetGroupLetrikEtara</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
