1 Executable JAR files
2 Define a main class in your JAR's MANIFEST.MF file that defines the executable class. (MANIFEST.MF is the file that Maven generates when packaging your application.)
3 Find all of the libraries on which your project depends.
4 Include those libraries in your MANIFEST.MF file so that your application classes can find them.
MANIFEST.MF is the file that Maven generates when packaging your application.
举例：
MANIFEST.MF
Manifest-Version: 1.0
Premain-Class: com.geekcap.openapm.jvm.agent.Agent
Can-Redefine-Classes: true
Can-Retransform-Classes: true
Can-Set-Native-Method-Prefix: true
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifestFile>
src/main/resources/META-INF/MANIFEST.MF
</manifestFile>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>
com.geekcap.openapm.ui.PerformanceAnalyzer
</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
This is an interesting example because it both defines a Premain-Class that allows the JAR file to work as a Java agent and has a mainClass that allows it to run as an executable JAR file. In this particular example, I've used OpenAPM (a code tracing tool that I built) to define code tracing that will be recorded by the Java agent and a user interface, which will facilitate analysis of recorded traces. In short, the example shows the power of combining an explicit manifest file with dynamic modifications.
