Specification-Version must not contain "-SNAPSHOT"
--------------------------------------------------
Key: MSHARED-191
URL: http://jira.codehaus.org/browse/MSHARED-191
Project: Maven Shared Components
Issue Type: Bug
Components: maven-archiver
Affects Versions: maven-archiver-2.4.1
Environment: Ubuntu 10.10, Maven 2.2.1 and Maven 3.0.3, OpenJDK
Runtime Environment (IcedTea6 1.9.7) (6b20-1.9.7-0ubuntu1) (64 bits)
Reporter: Romain Buquet
Attachments: patch maven-archiver
When building an artifact with a SNAPSHOT version,
Specification-Version and Implementation-Version are both set to ${pom.version}
(as described in the documentation).
But this will break the deployment in a container like WebLogic Server 10.3.4.
This behavior is compliant with specification
http://download.oracle.com/javase/6/docs/technotes/guides/versioning/spec/versioning2.html#wp89939
where it is said that "Specification version numbers use a Dewey decimal
notation consisting of numbers seperated by periods"
Further in this spec, in ยง "1.5.10 Rationale for limiting Implementation
version numbers to identity", it is explained why Implementation-Version need
to be compared strictly for equality.
So we can understand that:
- Specification-Version must NOT have "-SNAPSHOT" suffix. This is legal to keep
only the beginning of ${pom.version}, because it represents the spec version,
not the build ;
- Implementation-Version has to be set to ${pom.version} to represent the exact
version of the build.
This used to be the behavior in Maven 1:
