Main-class and Class-path configuration files when Maven projects generate jars

Write this blog mainly for their own later can quickly find.

Add the following build content to the project node of the Pom.xml file:

    <build> <plugins> <plugin> <groupid>org.apache.maven.plugi Ns</groupid> <artifactId>maven-jar-plugin</artifactId> <version>2. 3.2</version> <configuration> <archive> <
                            manifest> <!--change Addclasspath to True if Daks is desktop version--> <addClasspath>true</addClasspath> <classpathprefix>lib/</c
                            Lasspathprefix> <mainClass>com.daks.timesheethelper.App</mainClass>
                            <addDefaultImplementationEntries>true</addDefaultImplementationEntries> <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries> </mani
               Fest>         <manifestEntries> <Permissions>${Permissions}</Permissions>
                        <Caller-Allowable-Codebase>${Caller-Allowable-Codebase}</Caller-Allowable-Codebase>
            </manifestEntries> </archive> </configuration> </plugin> <plugin> &LT;GROUPID&GT;ORG.APACHE.MAVEN.PLUGINS&LT;/GROUPID&G
                T
                <artifactId>maven-dependency-plugin</artifactId> <version>2.3</version> <executions> <execution> <id>copy-dependencies</id&
                        Gt <phase>package</phase> <configuration> <overwrite Releases>false</overwritereleases> <overwritesnapshots>fAlse</overwritesnapshots> <overWriteIfNewer>true</overWriteIfNewer>
                            <outputDirectory> ${project.build.directory}/lib 
                            </outputDirectory> </configuration> <goals>
                    <goal>copy-dependencies</goal> </goals> </execution> </executions> </plugin> </plugins> & Lt;/build>

The end result is a Lib directory under target that contains some third-party jars that the project uses, or a jar of its own other projects, and then Main-class and Class-path configuration information in the MF file of the main jar package. This is the condition that guarantees that the jar package is executable.
