Maven - 使用-source 5或更高版本来启用...同时构建项目 [英] Maven - use -source 5 or higher to enable... while building the project

问题描述

我从我们的svn下载了一个项目，现在我正在尝试使用Maven构建它（mvn clean install ...我的maven是Apache Maven 3.0.4）。不幸的是，当我尝试构建时，会发生以下错误。奇怪的是它报告了一些关于Java版本1.3的东西（我认为），当然我没有在我的笔记本电脑中安装它。我有 JAVA_HOME 设置为JDK 1.7，我的javac也是1.7版本...

I downloaded one project from our svn and now I am trying to build this using Maven (mvn clean install... my maven is Apache Maven 3.0.4). Unfortunately, when I try to build, the following error occurs. It is strange that it reports something (I think) about Java version 1.3, which of course I dont have installed in my laptop. I have JAVA_HOME setted to JDK 1.7, my javac is also in version 1.7 ...

请知道吗问题出在哪里？

Please do you know where is the problem?

推荐答案

您必须为maven-compiler-plugin指定源配置参数，如下所示：

You must specify the source configuration parameter to the maven-compiler-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.5</source>
    </configuration>
  </plugin>

参见设置Java编译器的-source和-target 。
