【问题描述】：
我使用 Eclipse IDE 和 Windows 操作系统开发 java 应用程序。
我有这个问题：从 cmd 我的 maven 任务运行良好，但如果我从 eclipse 调用它 - 我看到 build failure
我想在我的 Eclipse 中使用带有 cmd 配置的 maven。
我做了以下步骤：
C:\>set m2_home
M2_HOME=C:\Program Files\apache\apache-maven-3.1.1
我只想从 Eclipse 执行与 cmd 相同的操作。
你能帮帮我吗？
更新——问题演示
来自 Eclipse：
我这样调用：
结果：

您能否发布更多来自 Eclipse 会话的 Maven 输出？查找以
[ERROR]开头的输出。还可以在 Maven 目标配置中添加-X选项，以显示 Maven 在失败时所做的极端细节。 -
@unhillbilly 请阅读更新
-
@unhillbilly 我在使用 java 7 时遇到了这个问题。似乎 ecilpse 使用 java 7。你知道在哪里可以切换我的 java 版本吗？
-
感谢您使用日志输出更新问题。是的，在使用 JDK 7（或 Android）时，这似乎是兼容性问题stackoverflow.com/a/8417510/55452。您的命令行 Maven 设置是否使用 JDK 6？如果是这样，请在您的 Eclipse 设置中使用 JDK 6（请参阅 Prefs->Java->Installed JREs），并让您的项目使用它（Java Build Path->Libraries）
-
@unhillbilly 真的，我切换了我的 java 版本，它对我有帮助。非常感谢！
