Question

POM.xml就像我在下面粘贴的那样。我尝试过oracle依赖，也有一些问题。我不明白两者之间有什么区别正常的POM和弹簧靴POM。我发现它有<parent> 解决版本冲突。除了我的POM中有什么错误我需要知道

请解释我的错误和解决方法。

我已经包含了环境变量的快照

Answer 1

这不是一个pom问题。将环境变量JAVA_HOME更改为指向jdk目录而不是jre。

Answer 2

错误告诉您您尝试使用Java运行时环境（JRE）编译Java类。您需要一个Java Development Kit（JDK）来编译java类。

解决方案：安装JDK并将JAVA_HOME环境变量更改为JDK目录。

Answer 3

最后两个步骤帮助我

1）构建路径---＆gt;删除JRE库并添加新属性标准VM 位置

2）在POM.xml中添加

<executable>C:\Program Files\Java\jdk1.7.0_79\bin\javac</executable>    
<fork>true</fork>
