gradle task腳本刪除log日志

正在學習gradle,所以不多說直接上代碼

在build.gradle中加入以下task，然后在Android Studio 的Terminal中執行，windows輸入gradlew -q dl,mac gradle -q dl，等一會你就發現所有Log.的代碼被刪除。

      task dl << {

      def rootPath = project.projectDir.absolutePath;

      def files = new File(rootPath + "/src");

      println files.getAbsolutePath()

      deleteLog(files)
    }

    void deleteLog(File listFiles) {
      if (listFiles != null) {
        listFiles.eachFile {File file ->
          if (file != null) {
            if (file.isFile()) {
              if (file.canRead() && file.name.endsWith(LogConstant.suffix)) {
                println file.getAbsolutePath()

                deleteFileLog(file);
              }
            } else if (file.isDirectory()) {
              deleteLog(file);
            }
          }
        }
      }
    }

    void deleteFileLog(File javafile) {
      def endFlag = 0;
      File ftmp = file(javafile.getAbsolutePath() + ".tmp");
      def printWriter = ftmp.newPrintWriter(LogConstant.charset);
      def reader = javafile.newReader(LogConstant.charset);
      def tmpline = null;
      String line;
      while ((line = reader.readLine()) != null) {
        if (line != null) {
          tmpline = line.trim();
          if (tmpline.startsWith(LogConstant.head) || endFlag == 1) {

            if (tmpline.endsWith(LogConstant.tail_end)) {
              endFlag = 0;
              printWriter.write(";\n")
              continue
            } else {
              endFlag = 1;
              continue
            }
          } else {
            printWriter.write(line + "\n");
          }
        }
      }

      reader.close();

      printWriter.flush();
      printWriter.close();

      javafile.delete();
      ftmp.renameTo(javafile.getAbsolutePath());
    }
