  • Method Details

    • getSource

      public String getSource()
      Description copied from interface: ModelProblem
      Gets the hint about the source of the problem. While the syntax of this hint is unspecified and depends on the creator of the problem, the general expectation is that the hint provides sufficient information to the user to track the problem back to its origin. A concrete example for such a source hint can be the file path or URL from which a POM was read.
      Specified by:
      getSource in interface ModelProblem
      Returns:
      The hint about the source of the problem or an empty string if unknown, never null.

    • getLineNumber

      public int getLineNumber()
      Description copied from interface: ModelProblem
      Gets the one-based index of the line containing the problem. The line number should refer to some text file that is given by ModelProblem.getSource().
      Specified by:
      getLineNumber in interface ModelProblem
      Returns:
      The one-based index of the line containing the problem or a non-positive value if unknown.

    • getColumnNumber

      public int getColumnNumber()
      Description copied from interface: ModelProblem
      Gets the one-based index of the column containing the problem. The column number should refer to some text file that is given by ModelProblem.getSource().
      Specified by:
      getColumnNumber in interface ModelProblem
      Returns:
      The one-based index of the column containing the problem or non-positive value if unknown.

    • getModelId

      public String getModelId()
      Description copied from interface: ModelProblem
      Gets the identifier of the model from which the problem originated. While the general form of this identifier is groupId:artifactId:version the returned identifier need not be complete. The identifier is derived from the information that is available at the point the problem occurs and as such merely serves as a best effort to provide information to the user to track the problem back to its origin.
      Specified by:
      getModelId in interface ModelProblem
      Returns:
      The identifier of the model from which the problem originated or an empty string if unknown, never null.

      The exception that caused this problem or null if not applicable.
