Question

由于maven故障导致通过命令行执行ant构建时出现问题。我可以毫无问题地构建eclipse，但是当尝试通过命令行执行时，Maven会阻塞并返回以下错误：

java.lang.NoSuchMethodError： org.apache.maven.artifact.ant.DependenciesTask.setPathType（Ljava /郎/字符串;）

我设置了环境变量M2 M2_HOME和JAVA_HOME。一切似乎都应该如此，但是当涉及到任何依赖方法或库时，我似乎无法弄清楚eclipse在空白处填充的位置。

Answer 1

正如评论中所提到的，Eclipse中使用的Maven Ant tasks版本与命令行中使用的版本之间存在差异。 Eclipse似乎正在使用此库的较新版本，其中方法DependenciesTask.setPathType(String)存在，而命令行依赖于旧版本。

通过查看首选项页面，您可以获得有关Eclipse正在使用的Ant任务版本的更多信息。尝试导航到窗口 - ＆gt;偏好 - ＆gt;蚂蚁 - ＆gt;运行时，并查看外部库的Classpath选项卡。

另一方面，从Ant构建的输出：

[echo] Executing maven build on Developer machine (other machine)
parsing buildfile jar:file:/C:/Apps/ANT/apache-ant-1.9.5/lib/maven-artifact-ant-2.0.4-dep.jar!/org/apache/maven/artifact/ant/antlib.xml with URI = jar:file:/C:/Apps/ANT/apache-ant-1.9.5/lib/maven-artifact-ant-2.0.4-dep.jar!/org/apache/maven/artifact/ant/antlib.xml from a zip file

命令行显然使用的是版本2.0.4，它位于Ant主目录的lib文件夹中。检查this page，最新版本是2.1.3，其中包含缺少的方法。因此，将Ant lib目录中的版本更新为最新版本是有意义的（检查项目页面上的下载链接）。

Answer 2

你总是可以针对用于eclipse的相同settings.xml运行maven（使用“-s”）

我们可以通过在调试移动中运行maven来获得更多描述：在运行maven时使用“-X”。

Answer 3

好的，这是确切的问题和解决方案......

我对几件事感到困惑。最初，我不清楚maven-ant-tasks和maven-artifact-ant是同一个库，我认为我需要安装maven-ant-tasks，但是这已经被原始响应清理了。其次，在研究如何更新（或安装）maven-ant-tasks时，我发现这已经在我的配置中发生，并且由于早在2.1.2就出现了正确的方法，我可以看到我们的以下配置系统是正确的，问题不应该发生

我的项目配置代码：

<taskdef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant">
  <classpath>
    <pathelement location="${basedir}/ant/lib/maven-ant-tasks-2.1.3.jar"/>
  </classpath>
</taskdef>

文档支持此处：http://maven.apache.org/ant-tasks/installation.html（代码略有不同，但目的和结果相同）

唉，问题仍在发生......在-verbose转储并比较eclipse构建输出和命令行输出之后，我可以看到唯一的区别是命令行试图同时调用它们文件，当它发生时，只加载了几个所需的方法。

在查看eclipse的ant目录后，我注意到maven-ant-tasks库根本就不存在，所以我尝试从我自己的安装中删除它和Voila！...我本来期望得到多态的结果，但显然这不起作用。
