我只是在学习 Maven，所以这可能很明显，但是我找不到一种简单的方法来列出给定项目的每个 Maven 生命周期阶段相关的目标。
我看到这里记录了 Maven 默认生命周期阶段和相应的默认目标。到目前为止，我的理解是每个 pom.xml 都可以将其他目标绑定到每个生命周期阶段。
那么，是否有一个 mvn 命令来确定给定项目的每个生命周期阶段将运行的目标？如果没有，我想我只需要查看每个新的 maven 项目的 pom.xml 就可以解决这个问题？

这buildplan-maven-plugin是显示目标如何绑定到阶段的绝佳工具。
以下是您可以运行的命令示例。如果尚未安装，这些命令将自动下载并安装插件。
按执行顺序列出目标

笔记
默认情况下，目标会搜索在用户调用时会运行的任务mvn deploy。clean不包括诸如此类的阶段。要在搜索中包含多个阶段，请使用以下buildplan.tasks属性：

mvn help:describe -Dcmd=compile（或任何其他有效阶段）

一个有用的工具是mvn help:effective-pom它将打印带有所有变量和所有父 POM 扩展的 POM。这有助于理解 Maven 所看到的。由此，很容易找到所有额外的目标（通常不是那么多）。
更大的问题是隐含的目标（即当插件自动挂钩到生命周期的某些阶段时）。如果不实际运行 Maven，就没有简单的方法来查看这些内容。这在 Maven 3 中应该会变得更好。在此之前，运行 Maven-X将打印大量调试输出以及当前阶段以及执行哪些插件。

如果不是使用 Maven 而是使用 m2e，您可以使用可以在 Eclipse 插件中使用的代码块来完成：
final IMavenProjectRegistry projectRegistry = MavenPlugin.getMavenProjectRegistry();
final IMavenProjectFacade facade = projectRegistry.getProject(project);
projectRegistry.execute(facade, new ICallable<Void>() {
public Void call(IMavenExecutionContext context, IProgressMonitor monitor) throws CoreException {
MavenProject mavenProject = facade.getMavenProject(monitor);
List<MojoExecution> mojoExecutions = ((MavenProjectFacade) facade).getMojoExecutions(monitor);
LifecycleMappingResult mappingResult = LifecycleMappingFactory.calculateLifecycleMapping(
mavenProject, mojoExecutions, facade.getResolverConfiguration().getLifecycleMappingId(),
monitor);
Map<MojoExecutionKey, List<IPluginExecutionMetadata>> mojoExecutionMapping = mappingResult
.getMojoExecutionMapping();
Map<String, List<MojoExecutionKey>> phases = new LinkedHashMap<String, List<MojoExecutionKey>>();
for (MojoExecutionKey execution : mojoExecutionMapping.keySet()) {
List<MojoExecutionKey> executions = phases.get(execution.getLifecyclePhase());
if (executions == null) {
executions = new ArrayList<MojoExecutionKey>();
phases.put(execution.getLifecyclePhase(), executions);
}
executions.add(execution);
}

它利用 m2e 计算目标与阶段关联的能力。我也在尝试在 Maven 级别解决它。

我将 Chad 的答案放入脚本中（这样我就不必记住很长的插件名称）。把它放在你的 ~/bin/ 文件夹中，这样你就可以在任何地方使用它。
