百度上说的jre我都试过了，我用的是jdk而且是1.8.
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project demo-test: Compilation failure说找不到3.1
但是我配置这个jar包换个版本却还是报错找不到3.1这个版本。

Answer 1

No compiler is provided in this environment 没选择jdk，编译没通过

Answer 2

不行啊，我多次配置jdk和jre都不行

Answer 3

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project demo-test: Compilation failure 主要是这个问题，大家帮忙解决以下。

Answer 4

你配置maven-compiler依赖的时候，里面有配JDK吗？

org.apache.maven.plugins
maven-compiler-plugin

1.7
1.7

Answer 5

IDE配置的java路径是一个jre不是一个jdk，去改下ide的配置就行了，在已安装java那把路径改成jdk的路径。sts默认是jre

Answer 6

你看看 你eclipse 的 maven 配置

Answer 7

非常感谢大家帮助，最终问题还是解决了，主要原因就是我安装的jdk不是放在c盘的指定目录，sts貌似只认c:\pro...file\java.....
我把jdk重新安装在默认的目录下就可以解决了。
