getResource

public static Optional<ResourceBundle> getResource(String pathToResource)

Return the resource at the given resource path in the resource directory META-INF/.

Parameters:

pathToResource -

Returns:

the resource at the given path, if exists.

getVersion

public static Optional<String> getVersion(String artifactId)

Return the version of the given artifact Id. This depends on a file with name "<artifactId>.properties" in the resource directory META-INF/. The file should contain a line that specifies the project version as "project.version".

Parameters:

artifactId -

Returns:

the version for the given artifactId

getSemVerGauge

public static double getSemVerGauge(String artifactId)

Return the version of the given artifact Id as a gauge value to be reported to Wavefront. This depends on a file with name "<artifactId>.properties" in the resource directory META-INF/. The file should contain a line that specifies the project version as "project.version". Format of semantic version gauge value reported to Wavefront = .<2-digit-minorVersion><2-digit-patchVersion> Ex: v2.6.1 => 2.0601

Parameters:

artifactId -

Returns:

the version Gauge value for the given artifactId
