Method Detail

enforceVersion

public void enforceVersion(Log log,
                           String variableName,
                           String requiredVersionRange,
                           ArtifactVersion actualVersion)
                    throws EnforcerRuleException

Compares the specified version to see if it is allowed by the defined version range.

Parameters:

log - the log

variableName - name of variable to use in messages (Example: "Maven" or "Java" etc).

requiredVersionRange - range of allowed versions.

actualVersion - the version to be checked.

Throws:

MojoExecutionException - if the version is not allowed.

EnforcerRuleException - the enforcer rule exception

containsVersion

public static boolean containsVersion(VersionRange allowedRange,
                                      ArtifactVersion theVersion)

Copied from Artifact.VersionRange. This is tweaked to handle singular ranges properly. Currently the default containsVersion method assumes a singular version means allow everything. This method assumes that "2.0.4" == "[2.0.4,)"

Parameters:

allowedRange - range of allowed versions.

theVersion - the version to be checked.

Returns:

true if the version is contained by the range.

getCacheId

public String getCacheId()

isCacheable

public boolean isCacheable()

isResultValid

public boolean isResultValid(EnforcerRule theCachedRule)

getVersion

public String getVersion()

Gets the required version.

Returns:

the required version

setVersion

public void setVersion(String theVersion)

Sets the required version.

Parameters:
