Gradle - how to iterate in fileTree only for certain type of file


in my gradle task I iterate through fileTree and all works good:

myTask {
  fileTree("${project.projectDir}/dir").visit { FileVisitDetails details ->
    exec {
      //do some operations
    }
  }
}

but now I have different types of files in my directory:

dir
├── sub1
│   ├── file1.json
│   └── file2.js
├── sub2
│   ├── file1.json
│   └── file2.js
└── sub3
    ├── file1.js
    └── file2.json

How to iterate for only certain type of files? Because

"${project.projectDir}/folder/dir/**/*.json"

doesnt work.

Thanks for any advice


Solution

  • You should use the matching method from FileTree. It uses a PatternFilterable as parameter.

    Try that :

    fileTree("${project.projectDir}/dir").matching {
        include "**/*.json"
    }.each {
        // do some operations
    }
