在 maven 中使用 findbugs-maven-plugin 时收到"Unable to create Maven project for com.sun:tools:pom:1.6 from

这是我的pom.xml 的<reporting>部分

<reporting>

当我运行"mvn站点"时，我收到了一条警告，上面写着

[WARNING] Unable to create Maven project for com.sun:tools:pom:1.6 from repository.

以下是警告的上下文：

我使用的是Java 1.8_u20和maven 3.2.1。

有人能帮忙解决这个问题吗？

这里是完整的输出日志

您在某个地方使用com.sun:tools吗？此依赖项应包含在系统范围内。

请参阅以下问题：

Maven：POM.xml 中缺少工件com.sun:tools:jar:1.6.0编译时异常

下面是一个如何正确操作的例子（使用配置文件使其也能在Mac上工作）：

<!--  JDK dependencies  -->
