java - 无法再在 Eclipse 上运行 Maven 安装(找不到tools.jar)

Question

我正在 ubuntu 16.04 上工作，我有一个 eclipse 项目，我无法再编译了。每次我尝试时都会出现此错误:

 [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]

首先我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)。

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

但问题是 openJDK8 有 JDK + JRE 对吧？ 我完全迷失在这里

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，

右键单击您的项目，“构建路径”->“配置构建路径”。在右侧选项中选择“JRE System Library”选择编辑，然后配置您的JDK
