The documentation for the <inceptionYear> tag in http://maven.apache.org/xsd/maven-4.0.0.xsd says:
The year of the project's inception, specified with 4 digits. This value is used when generating copyright notices as well as being informational. CHANGES.txt indicates that Lucene's first open source release (v0.01) was in 2000. Shouldn't this be changed to <inceptionYear>2000</inceptionYear> ? Steve
