无法再在 Eclipse 上运行 Maven 安装（未找到 tools.jar）

Question

我正在开发 ubuntu 16.04，我有一个无法编译的 Eclipse 项目。每次我尝试我都会遇到这个错误：

 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5:compile (default-compile) on project TwavoxManager: Fatal error compiling: tools.jar not found: /usr/lib/jvm/java-8-openjdk-amd64/jre/../lib/tools.jar -> [Help 1]

我首先可以毫无问题地编译它，但我必须在我的系统上重新安装 java (openJDK8)。

我尝试了这个链接Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin (default-compile) on project: Fatal error compiling: tools.jar not found的解决方案

但问题是 openJDK8 有 JDK + JRE 对吗？ 我完全迷失了这里

编辑：添加 pom.xml：

更新 pom.xml 中的插件条目，

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>

并配置项目JDK，

右击你的项目，Build Path->Configure Build Path。在右侧选项中选择“JRE System Library”选择编辑然后配置你的JDK
