无法在MAVEN EXPORT中找到Javac编译器

Question

我想用maven导出Java项目。但我成了这个错误：

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project craftbukkit: Compilation failure
[ERROR] Unable to locate the Javac Compiler in:
[ERROR] C:\Program Files\Java\jre8\..\lib\tools.jar
[ERROR] Please ensure you are using JDK 1.4 or above and
[ERROR] not a JRE (the com.sun.tools.javac.Main class is required).
[ERROR] In most cases you can change the location of your Java
[ERROR] installation by setting the JAVA_HOME environment variable.
[ERROR] -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:

我已经将我的JAVA设置为此目录：

C:\Program Files\Java\jdk1.8.0

我该怎么做，它有效吗？

谢谢！

Answer 1

你可以尝试一下：

1. 如果您在Eclipse中，则可以检查已安装的JRE。
2. 尝试更新版本的maven-compiler-plugin并设置源和目标版本。
3. Echo $ JAVA_HOME并确保它引用您提到的位置。
4. 尝试javac java代码以更加确定您的默认java编译器。
5. 使用mvn包程序集：单个用于导出。
