Java 未能执行目标org.apache.maven.plugins:maven编译器plugin:2.0:compile

我正在研究SpringMVC[谷歌应用程序引擎]。我的项目是基于1.6JavaSDK构建的，以前我想切换到JavaSDK1.7

我已经为更新到Java1.7SDK做了所有更改

我在pom.xml文件中做了更改[我对旧的1.6 SDK代码进行了注释]

org.apache.maven.plugins
maven编译器插件
2
C:/ProgramFiles/Java/jdk1.7.0_45/bin/javac
1.7
1.7

但当使用Maven安装命令时，我得到的异常是

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0:compile

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0:compile (default-compile) on project: Compilation failure

您应该发布更多的maven输出。这一行没有告诉我们任何事情。如果编译失败，实际编译错误的输出位于第

[ERROR]行编译错误之后：

。您的输出是否包含该行？对于所有文件，错误显示：无法解析错误消息：symbol:class Table[error]import javax.persistence.ManyToOne^你确定你在使用Maven 3吗？Maven 2和Java 7有一个问题，导致您给出的错误消息。有关更多信息，请参见此处：听起来您真的在使用maven 3。您是否尝试过更新编译器插件的版本？2.0.0已经很老了。
