[jira] [Commented] (FELIX-6304) bundle:bundle generates
non-reproducible JAR archives (timestamps)
[ https://issues.apache.org/jira/browse/FELIX-6304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17306943#comment-17306943 ]
Jochen Schalanda commented on FELIX-6304:
-----------------------------------------
{quote}That's not directly a maven-bundle-plugin issue, but more bnd instructions used. Using bnd {{-reproducible}} flag (or {{_reproducible}} in the {{maven-bundle-plugin}}).
{quote}
That's what I would've done in the beginning if the flag had been documented anywhere. ;)
[https://felix.apache.org/components/bundle-plugin/] doesn't mention the reproducible flag anywhere, neither does [https://felix.apache.org/].

> 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: [https://github.com/apache/maven-jar-plugin/commit/64c5e6530b4712cd95501fffb2de6bb1a202cd89]
