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.

getException

public Exception getException()

Description copied from interface: ModelProblem

Gets the exception that caused this problem (if any).

Specified by:

getException in interface ModelProblem

Returns:

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

getMessage

public String getMessage()

Description copied from interface: ModelProblem

Gets the message that describes this problem.

Specified by:

getMessage in interface ModelProblem

Returns:

The message describing this problem, never null.

getSeverity

public ModelProblem.Severity getSeverity()

Description copied from interface: ModelProblem

Gets the severity level of this problem.

Specified by:

getSeverity in interface ModelProblem

Returns:

The severity level of this problem, never null.

toString

public String toString()

Overrides:

toString in class Object
