看到第二行 resolution will not be reattempted until the update interval of apache.snapshots 有这么一句话,于是打算更新项目,右击项目,选择强制更新
但是报错还是没有消除,于是我右击项目,如下图
在 pom 中引入 tools.jar
<dependency>
<groupId>jdk.tools</groupId>
<artifactId>jdk.tools</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${JAVA_HOME}/lib/tools.jar</systemPath>
</dependency>
保存之后问题解决。
正文完
