We dug through the log file (catalina.out) and didn't see anything interesting that might be relevant :/

Well I just found our first clue!

I noticed that the "shelve project" button does in fact appear, but it does so on the wrong page. It appears on each of the matrix platforms, instead of the project page.

That is, it does not show up here:

.../view/job/foo-product/

but it does show up here:

.../view/job/foo-product/label=windows-64.build/

Jenkins ver. 1.423, plugin ver. 1.3

The same problem on our Jenkins installation: the 'Shelved Projects' link is not shown in some projects.

The interesting thing happens when a new project created as copy of the project missing the 'Shelved Projects' link:
on the first open Configure page the 'Shelved Projects' link is present, but it disappears on next page after 'Save' button is pressed.

See attached config.xml as a sample of such problem project.

I recently unshelved some projects.

Now I'm done with them & want to pack them back up, but none of them has a Shelve Project link anymore

A recent Jenkins restart restored the 'Shelve' buttons. So it appears that the piece that runs at startup also needs to be invoked @unshelve.

I'm guessing that the 'shelve' action is removed onShelve. So the other option m.ight be to just not do that

I have noticed a similar (same?) problem to that reported. Here are the specifics in case there's useful information:

We're running Jenkins v1.442 and tried installing and running the shelve plugin (v1.3) without a restart. The "Shelve Project" link didn't appear on any of the job pages though "Shelved Projects" was visible on the main page.

Restarting Jenkins fixed the issue; all jobs now have the "Shelve Project" option.

Looks like when a job is created using "Copy existing job", the properties are not copied with it. The newly created job is missing this property which allows it to be shelved. I made following change in the job and restarted Jenkins and can now see the Shelve button. (I know the workaround sucks). Don't know if this is a defect in the plugin or core/create job functionality.

— SNIP —
<properties>
<org.jvnet.hudson.plugins.shelveproject.ShelveProjectProperty/>
</properties>
— SNIP —

It looks like the job configuration loses the ShelveProjectProperty while being saved by the user, i.e. by clicking the "Save" button. If the system changes the job configuration for its own needs the property becomes restored and the "Shelve project" link appears again... up to the next saving by user.

BTW, does anybody work on this plugin yet?

I am also seeing this on my Jenkins instance (v1.460) running RHEL. Is anyone looking into this?

We are also seeing this with Jenkins 1.464 on Windows 7. Seems to happen for new projects, perhaps the ones created by the Copy From option. Our fix is to restart the Jenkins service, then we can shelve.

Experienced the same issue with Jenkins 1.514 and Shelve Projects 1.3. Restarting Jenkins restored the Shelve Project button.

Same here, Jenkins 1.529, Shelve Projects 1.4.4. Restarting helped.

Fix to persist Shelve project property whenever the job is updated
this fix would resolve JENKINS-10544

maselvaraj's pull request corrects this problem. It'll be included in the next rev of this plugin.

Fixed in release v 1.5

I just installed Shelve Project(V1.5) plugin and this option is still missing.

I just installed Shelve Project(V1.5) plugin and this option is still missing.

Fix made to JENKINS-39239 should fix this issue. I'll close as fixed, please reopen if you encounter the issue for a version <= 2.1 of the plugin

I am facing this error now. I have installed the plugin today and I don't see the shelve project option for any job. I have 2.1 version installed and Jenkins 2.129.

jigel_raja: Can you please provide more details, what is the type of job not displaying the shelve option?

pierrebtz all of them are pipelines. None of them have the shelve option on their pages. I created a freestyle projet and it also doesn't have the option.

jigel_raja : Pipeline us expected as the plugin doesn't support them yet, I hope I'll have some time to add support soon!

Freestyle on the other hand is clearly a bug, can you please send a screenshot of the freestyle job page.
If you just upgraded the plugin, did you restart your Jenkins instance?

jigel_raja were you able to reproduce the issue on a Freestyle job?

jigel_raja I'll close as not reproduced, please reopen if you have a test case.
