maven 打包可执行jar的方法

阅读更多

在这之前，我自己找了点maven的东西添加进来

Maven内置变量说明：
    ${basedir} 项目根目录
    ${project.build.directory} 构建目录，缺省为target
    ${project.build.outputDirectory} 构建过程输出目录，缺省为target/classes
    ${project.build.finalName} 产出物名称，缺省为${project.artifactId}-${project.version}
    ${project.packaging} 打包类型，缺省为jar
    ${project.xxx} 当前pom文件的任意节点的内容

 

 

 

方式1

修改pom.xml增加如下内容

< plugin >
    < groupId >org.apache.maven.plugins groupId >
    < artifactId >maven-jar-plugin artifactId >
    < version >2.4 version >
    < configuration >
        < archive >
            < manifest >
                < addClasspath >true addClasspath >
                < classpathPrefix >lib/ classpathPrefix >
                < mainClass >com.sysware.HelloWorld mainClass >
            manifest >
        archive >
    configuration >
plugin >

运行mvn clean package即可

批注：

经过我本人自测之后发现，这种方式虽然可以打包，但是不会将依赖包也添加进去。所以我认为这种方式的打包适合写一个工具，然后打成JAR包，导入其他工程使用，如果是一个单独运行的JAR包，则不适用。

方式2

在pom.xml增加如下内容

< plugin >
    < groupId >org.apache.maven.plugins groupId >
    < artifactId >maven-assembly-plugin artifactId >
    < version >2.3 version >
    < configuration >
        < appendAssemblyId >false appendAssemblyId >
        < descriptorRefs >
            < descriptorRef >jar-with-dependencies descriptorRef >
        descriptorRefs >
        < archive >
            < manifest >
                < mainClass >com.juvenxu.mvnbook.helloworld.HelloWorld mainClass >
            manifest >
        archive >
    configuration >
    < executions >
        < execution >
            < id >make-assembly id >
            < phase >package phase >
            < goals >
                < goal >assembly goal >
            goals >
        execution >
    executions >
plugin >

运行mvn assembly:assembly （我自己使用mvn clean package也是可以的）

批注：

这个方式和方式1不同，这种打包方式，将项目及所依赖的所有jar包打包成一个jar，让打出来的JAR包成为一个可独立运行的JAR包

方式3

批注：

    我自己在博主的基础上，添加了一些配置和注释

    方式3和方式4都是比较复杂的打包方式，但是可以自己定义细节，比如需要哪些文件被打包，哪些文件不打包进去，哪些文件放到哪里等等。
