在使用eclipse过程中Maven构建项目过程中报错

No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

原因是eclipse的环境配置有问题，
windows-preferences-java-installed JREs中配置为jre
而maven的conf/settings.xml中配置为JDK

    <profile>
      <id>jdk-1.8</id>
      <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
      </activation>
      <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
      </properties>
    </profile>

因此产生冲突

解决方案：

将eclipse中installed-JREs内容替换为JDK

1，点击add

2.选择standard VM next>

3 JRE home 点击 directory 选择JDK目录

点击finish
apply and close

---

到此，环境配置更新完成，但是需要将已经建好的Maven项目修改下配置

项目右键 build path – configure build path

libraries标签下

选中JRE System Library , 点击edit

选择JDK
applyandclose

然后再compile

构建成功
