我在博客上写了一些不同的方法来做到这一点。
参见带有Apache Maven的可执行Jar（WordPress）
或可执行文件罐与Maven示例（GitHub）
笔记
这些优点和缺点由Stephan提供。
对于手动部署
将依赖项复制到特定目录
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/${project.build.finalName}.lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
使Jar可执行并具有Classpath意识
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>${project.build.finalName}.lib/</classpathPrefix>
<mainClass>${fully.qualified.main.class}</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
此时，jar实际上可以使用外部classpath元素执行。
$ java -jar target/${project.build.finalName}.jar
制作可部署的档案
该jar文件只能在同级...lib/目录中执行。我们需要创建存档以与目录及其内容一起部署。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>antrun-archive</id>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<property name="final.name" value="${project.build.directory}/${project.build.finalName}"/>
<property name="archive.includes" value="${project.build.finalName}.${project.packaging} ${project.build.finalName}.lib/*"/>
<property name="tar.destfile" value="${final.name}.tar"/>
<zip basedir="${project.build.directory}" destfile="${final.name}.zip" includes="${archive.includes}" />
<tar basedir="${project.build.directory}" destfile="${tar.destfile}" includes="${archive.includes}" />
<gzip src="${tar.destfile}" destfile="${tar.destfile}.gz" />
<bzip2 src="${tar.destfile}" destfile="${tar.destfile}.bz2" />
</target>
</configuration>
</execution>
</executions>
</plugin>
现在，您target/${project.build.finalName}.(zip|tar|tar.bz2|tar.gz)每个都包含jar和lib/*。
Apache Maven Assembly插件
- 优点
- 缺点
- 不支持类重定位（如果需要类重定位，请使用maven-shade-plugin）。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>${fully.qualified.main.class}</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
你有target/${project.bulid.finalName}-jar-with-dependencies.jar。
Apache Maven Shade插件
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<shadedArtifactAttached>true</shadedArtifactAttached>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>${fully.qualified.main.class}</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
你有target/${project.build.finalName}-shaded.jar。
onejar-maven-plugin
<plugin>
<!--groupId>org.dstovall</groupId--> <!-- not available on the central -->
<groupId>com.jolira</groupId>
<artifactId>onejar-maven-plugin</artifactId>
<executions>
<execution>
<configuration>
<mainClass>${fully.qualified.main.class}</mainClass>
<attachToBuild>true</attachToBuild>
<!-- https://code.google.com/p/onejar-maven-plugin/issues/detail?id=8 -->
<!--classifier>onejar</classifier-->
<filename>${project.build.finalName}-onejar.${project.packaging}</filename>
</configuration>
<goals>
<goal>one-jar</goal>
</goals>
</execution>
</executions>
</plugin>
Spring Boot Maven插件
- 优点
- 缺点
- 添加潜在的不必要的Spring和Spring Boot相关类。
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>spring-boot</classifier>
<mainClass>${fully.qualified.main.class}</mainClass>
</configuration>
</execution>
</executions>
</plugin>
你有target/${project.bulid.finalName}-spring-boot.jar。
