我不是非常有经验与Maven与Android的组合，因此我跟着这些的说明进行新的Andr​​oid项目。当已创建项目，我收到以下错误信息：

I'm not very experienced with Maven in combination with Android yet, so I followed these instructions to make a new Android project. When the project has been created, I get the following error message:

项目XXX-1.0-快照缺少所需的源文件夹：   SRC /测试/ java的

Project 'xxx-1.0-SNAPSHOT' is missing required source folder: 'src/test/java'

当我尝试添加一个新的源文件夹中新建 - >其他 - > Java的源文件夹使用的src /测试/ java中，我得到另一个错误信息：

When I try to add a new source folder with New->Other->Java-Source Folder with src/test/java, I get another error message:

文件夹已经是源文件夹。

The folder is already a source folder.

不过，我没有任何的src /测试/ java文件夹在我的项目。我应该如何处理呢？什么是干净的方式来设置这个项目，是因为我认为也有一些是在该指令失踪。那么，什么是Maven的方法，让SRC /测试/ java的出现？

But I don't have any src/test/java folder in my project. How should I deal with that? What's the clean way to setup the project, because I assume that there is something missing in this instruction. So what is the Maven way to let src/test/java appear?

我使用Eclipse的Juno，M2E 1.1.0，Android的配置M2E 0.4.2。

I'm using Eclipse Juno, m2e 1.1.0, Android Configuration for m2e 0.4.2.

推荐答案

我意识到这恼人的事情太多，因为最新的M2E-Android插件升级（0.4.2版本），它发生在这两个新项目的创建和现有项目导入（如果你不使用的src /测试/爪哇）。

I realise this annoying thing too since latest m2e-android plugin upgrade (version 0.4.2), it happens in both new project creation and existing project import (if you don't use src/test/java).

它看起来像M2E-机器人（或者M2E）现在总是试图添加的src /测试/ java的作为源文件夹，无论是实际存在的项目目录，在.classpath文件：

It looks like m2e-android (or perhaps m2e) now always trying to add src/test/java as a source folder, regardless of whether it is actually existed in your project directory, in the .classpath file:

<classpathentry kind="src" output="bin/classes" path="src/test/java">
  <attributes>
    <attribute name="maven.pomderived" value="true"/>
  </attributes>
</classpathentry>

因为它是在项目的元数据文件已经增加，因此，如果你想添加通过Eclipse的源文件夹，Eclipse会抱怨classpathentry是已经存在的：

As it is already added in the project metadata file, so if you trying to add the source folder via Eclipse, Eclipse will complain that the classpathentry is already exist:

有几种方法可以解决这个问题，最简单的是手动在文件系统中创建的src /测试/ java目录，然后通过preSS F5 和运行Maven刷新您的项目 - >更新项目（右键项目，选择Maven的 - >更新项目...），这应该可以解决缺少必要的源文件夹：SRC /测试/ java的错误

There are several ways to fix it, the easiest is manually create src/test/java directory in the file system, then refresh your project by press F5 and run Maven -> Update Project (Right click project, choose Maven -> Update Project...), this should fix the missing required source folder: 'src/test/java' error.
