Method Detail

readVersionNumber

public static String readVersionNumber(String resourcePath)

Reads a version number from a properties file on the classpath. These files are generally created by Maven. For example, tapestry-core's properties file is META-INF/maven/org.apache.tapestry/tapestry-core/pom.properties. The Maven generated properties files include the artifact id and group id as well as the version.

The resource is located using the Thread's context class loader.

Parameters:

resourcePath - the complete path to the resource, including a leading slash.

Returns:

the version number read from the properties file, or "UNKNOWN" if the version number is not present or the file can not be opened
