    • createCommandLine

      public String[] createCommandLine(CompilerConfiguration config) throws CompilerException
      Description copied from interface: Compiler
      Create the command line that would be executed using this configuration. If this particular compiler has no concept of a command line then returns null.
      Parameters:

    • buildCompilerArguments

      public static String[] buildCompilerArguments(CompilerConfiguration config, String[] sourceFiles)

    • isPreJava14

      private static boolean isPreJava14(CompilerConfiguration config)
      Determine if the compiler is a version prior to 1.4. This is needed as 1.3 and earlier did not support -source or -encoding parameters
      Parameters:
      config - The compiler configuration to test.
      Returns:
      true if the compiler configuration represents a Java 1.4 compiler or later, false otherwise

    • isPreJava16

      private static boolean isPreJava16(CompilerConfiguration config)
      Determine if the compiler is a version prior to 1.6. This is needed for annotation processing parameters.
      Parameters:
      config - The compiler configuration to test.
      Returns:
      true if the compiler configuration represents a Java 1.6 compiler or later, false otherwise
