Maven插件开发

首先使用命令创建Maven工程：

mvn archetype:generate -DgroupId=groupId -DartifactId=artifactId -DarchetypeArtifactId=maven-archetype-mojo

然后想在Eclipse下编辑工程，使用下面的命令把工程进行了转化：

mvn eclipse:eclipse

完成后新建class：

@Mojo(name="instrument", requiresDependencyResolution=ResolutionScope.COMPILE, defaultPhase=LifecyclePhase.VALIDATE)public class xxxMojo extends AbstractMojo {public void execute() throws MojoExecutionException {String nameOfRunningVM = ManagementFactory.getRuntimeMXBean().getName();int p = nameOfRunningVM.indexOf('@');String pid = nameOfRunningVM.substring(0, p);String jarFilePath = null;getLog().info("Dynamically loading xxx instrumentation...");try {jarFilePath = xxx.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath().toString();jarFilePath = new File(jarFilePath).getCanonicalPath();getLog().info("Found xxx instrumentation within " + jarFilePath);} catch (URISyntaxException e) {getLog().error("Unable to find xxx instrumentation jar");throw new RuntimeException(e);} catch (IOException e) {getLog().error("Unable to find xxx instrumentation jar");throw new RuntimeException(e);}try {VirtualMachine vm = VirtualMachine.attach(pid);vm.loadAgent(jarFilePath, System.getProperty("xxx.AgentArgs"));vm.detach();} catch (Exception e) {getLog().error("Error encountered while loading the xxx agent", e);throw new RuntimeException(e);}}}

修改pom.xml：

mvn clean install

生成插件并安装到本地库

另外在记录一下：

添加单个jar到maven本地仓库的操作如下：
1.建立一个新的文件夹，将jar文件存放在该文件夹下。注意文件夹下最好只存放该文件。
2.在cmd窗口中执行以下命令： mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
例如：
mvn install:install-file -Dfile=xxx.jar -DgroupId=xxx -DartifactId=xxx -Dversion=1.0.0 -Dpackaging=jar
