maven项目配置native-image插件使用tracing-agent跑单测生成reachability metadata

                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

如果发现生成的reachability metadata文件存在无关的class，可以配置filter文件来过滤掉：
在option标签下设置

<options>
    <callerFilterFiles>
        <filterFile>caller-filter-file1.json</filterFile>
        <filterFile>caller-filter-file2.json</filterFile>
    </callerFilterFiles>
    <accessFilterFiles>
        <filterFile>access-filter-file1.json</filterFile>
        <filterFile>access-filter-file2.json</filterFile>
    </accessFilterFiles>
</options>

参考的access filter file文件：

{
  "rules": [
    {
      "excludeClasses": "org.apache.maven.**"
    },
    {
      "excludeClasses": "org.mockito.**"
    },
    {
      "excludeClasses": "libcore.io.Memory"
    },
    {
      "excludeClasses": "org.powermock.**"
    },
    {
      "includeClasses": "com..**"
    }
  ]
}
