BJ Hargrave commented on FELIX-6304:
------------------------------------
It would be better if maven-bundle-plugin looked to see if the project property
`project.build.outputTimestamp` was set (non-null) and if so, then
maven-bundle-plugin should set `-reproducible: true` on the underlying Bnd
Builder object. Then you don't require users to configure a specific Bnd
instruction but instead use the normal maven way to configure for reproducible
builds which is to set the `project.build.outputTimestamp` project property.
> bundle:bundle generates non-reproducible JAR archives (timestamps)

> Key: FELIX-6304
> URL: https://issues.apache.org/jira/browse/FELIX-6304
> Project: Felix
> Issue Type: Bug
> Components: Maven Bundle Plugin
> Affects Versions: maven-bundle-plugin-5.1.1
> Reporter: Jochen Schalanda
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Labels: reproducible-builds
>
> The JAR archives built by maven-bundle-plugin are not reproducible (as in
> reproducible builds) because the timestamps of their entries are variable and
> are using the current system time.
> The maven-jar-plugin supports using a fixed timestamp via the
> [outputTimestamp|https://maven.apache.org/plugins/maven-jar-plugin/jar-mojo.html#outputTimestamp]
> setting (default: {{${project.build.outputTimestamp}}}) while the
> maven-bundle-plugin doesn't expose a similar setting.
> Support for reproducible builds in the maven-jar-plugin was added with this
> commit:
