1. Manually modify the
/META-INF/ MANIFEST.MF
ordinary jar package
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Built-By: Administrator
Created-By: Apache Maven 3.3.3
Build-Jdk: 1.8.0_171
to change Into an executable jar package, you need to specify main
Main-Class: com.my.jvm.AssemblyTest.
If the jar package depends on other third-party jars, you must also specify Class-Path
Class-Path: lib/log4j-1.2.17.jar lib /slf4j-log4j12-1.7.21.jar lib/slf4 2. Assembly
plug-in: also type in the related dependency packages and execute them through assembly: assembly under plugins. The disadvantage is that the spirng project may report errors (not verified).
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.my.jvm.AssemblyTest</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>
jar-with-dependencies
</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
3. Shade plug-in (recommended), the function is the same as assembly, directly executed by mvn package
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.1</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.my.jvm.AssemblyTest</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
4. maven-jar-plugin (recommended), the advantage is that no dependencies are packaged, and the package that comes out is very small, directly execute mvn package
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>make-a-jar</id>
<phase>compile</phase>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.my.jvm.AssemblyTest</mainClass>
</manifest>
</archive>
<excludes>
<exclude>*.properties</exclude>
<exclude>*.txt</exclude>
</excludes>
</configuration>
</plugin>
