由于某种原因，maven assembly：single抛出以下错误。但是，maven-assembly-plugin依赖关系树未显示jmxtools。 Maven Central没有jar文件。 http://central.maven.org/maven2/com/sun/jdmk/jmxtools/1.2.1/ 我很困惑，我想念什么？任何帮助表示赞赏。
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:3.1.0:single (ci) on project extracense: Failed to create assembly: Error creating assembly archive ci: C:\Users\v493289\.m2\repository\com\sun\jdmk\jmxtools\1.2.1\jmxtools-1.2.1.jar -> [Help 1]
这是Maven依赖树。
