Nexus 2 : Task execution failure; Error rendering template /repositoryContentHtml.vm

Post by ian.williams1 on Aug 6, 2022

Environment: Nexus Repository Manager OSS 2.15.1-02 on Linux VM

We have observed the following pair of errors listed at bottom, titled : Task execution failure.

Following response on prior (old) support ( #36990)

To fix this, shut down Nexus, and rename “sonatype-work/nexus/indexer” to

“sonatype-work/nexus/indexer.old”.

Then restart, and go to “administration/scheduled tasks” and create and run a repair indexes task against all repositories.

Upon reindexing completion, observed the following (sanitized) logs:

WARN  [qtp1658920240-34] anonymous org.sonatype.nexus.content.internal.ContentServlet - java.io.IOException: Template processing error: org.apache.velocity.exception.VelocityException: IO Error rendering template '/org/sonatype/nexus/content/internal/repositoryContentHtml.vm', caused by: org.apache.velocity.exception.VelocityException: IO Error rendering template '/org/sonatype/nexus/content/internal/repositoryContentHtml.vm', caused by: org.eclipse.jetty.io.EofException, caused by: java.io.IOException: Broken pipe [client=,ua=Wget/1.14 (linux-gnu),req=GET http://mavenrepository.corp/nexus/content/repositories/deployables-thirdparty/corp/custom/path/to//groupID/]

INFO  [SessionValidationThread-1]  org.apache.shiro.session.mgt.AbstractValidatingSessionManager - Finished session validation.  No sessions were stopped.

I can confirm /deployables-thirdparty/corp/custom/path/to/groupID/ (single slash to/groupID) exists and has 3422 elements / versions inside. Not clear why the logs show “//`” or if that’s related to the error.

Please advise if there is in fact an error, and if it is user resolvable..

Update: Further examination of the logs shows the error ( repositoryContentHtml.vm ) predates the reported Task Execution failures (Download Central Index and Download Central Index).

The repositoryContentHtml.vm** occurs up to 15x / day for 62 of the 90 days (some days skipped) of prior logs; the reindexing only drew our attention to its existence.

Originating Task Execution Failures:

Task ID: 13
Task Name: Download Central Index
Stack trace:
java.io.IOException: Cannot fetch remote index for repository "Central" [id=central], error occurred.
