SonarQube Web API在项目级别显示0％的重复，尽管在文件级别有些重复

Question

我正在使用SonarQube（版本6.7.2（内部版本37468））Web API来检索项目上的重复量。   但是有一个奇怪的行为：问

http://10.117.72.197:9000/api/duplications/show?key=com.my.project:my-project

我明白了

{"duplications":[],"files":{}}

询问时

http://server:9000/api/duplications/show?key=com.my.project:my-project:src%2Fmain%2Fjava%2Fcom%2Fmy%2Fproject%2FMyFile.java

我知道

{"duplications":[{"blocks":[{"from":489,"size":16,"_ref":"1"},{"from":520,"size":14,"_ref":"1"}]}],"files":{"1":{"key":"...","name":"...","uuid":"...","project":"...","projectUuid":"...","projectName":"...","subProject":"...","subProjectUuid":"...","subProjectName":"..."}}}

如何获得全局结果而不必在项目的每个文件上调用API？

谢谢！
