Interface ModelProblem

All Known Implementing Classes:

getSource

String getSource()

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.

Returns:

The hint about the source of the problem or an empty string if unknown, never null.

getLineNumber

int getLineNumber()

Gets the one-based index of the line containing the problem. The line number should refer to some text file that is given by getSource().

Returns:

The one-based index of the line containing the problem or a non-positive value if unknown.

getColumnNumber

int getColumnNumber()

Gets the one-based index of the column containing the problem. The column number should refer to some text file that is given by getSource().

Returns:

The one-based index of the column containing the problem or non-positive value if unknown.

getModelId

String getModelId()

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.

Returns:

The identifier of the model from which the problem originated or an empty string if unknown, never null.

getException

Exception getException()

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

Returns:

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

getMessage

String getMessage()

Gets the message that describes this problem.

Returns:

The message describing this problem, never null.

getSeverity

ModelProblem.Severity getSeverity()

Gets the severity level of this problem.

Returns:

The severity level of this problem, never null.

getVersion

ModelProblem.Version getVersion()

Gets the applicable maven version/validation level of this problem

Returns:

The version, never null.
