Rafael Pestano added a comment - 2018-01-25 20:48 - edited Hi, which version of Last changes are you using? If It is 2.5 can you try to downgrade to V2.4?

Emil Wypych added a comment - 2018-01-25 21:20 rmpestano hi! I've been using v2.5 and I downgraded to 2.4 as you suggested. The problem has not been solved. I still see those messages even after downgrade: Jan 25, 2018 10:08:49 PM WARNING jenkins.security.ClassFilterImpl lambda$isBlacklisted$1 java.text.SimpleDateFormat in JRE might be dangerous, so

marked as failed. Console output says that they have ended with success, but in the build history of each job builds are marked as failed. Also, those builds aren't marked as successful neither failed in the job list (columns Last Success and Last Failures don't have those builds). Before downgrade builds were marked properly. Also after the downgrade, I cannot see the last changes - there is no "View Last Changes" link in the builds which has been started on Last Changes Plugin v2.5. In the new builds (after downgrade) everything is ok. Of course, I could check Last Changes when Last Changes was in version 2.5 - I checked this.

Rafael Pestano added a comment - 2018-01-25 21:50 Hi again,   I think you need to create a new job to test the v2.4.    Anyway, I'll make some tests here. Thanks for reporting.

Rafael Pestano added a comment - 2018-01-25 22:35 - edited Hi ewypych ,  I've made some test (with and without pipeline) using jenkins 2.103 and had no issues, do you have more details? I've tested with a clean jenkins installation using this Dockerfile (I've only changed jenkins version).The plugins versions I'm using can be found here: https://github.com/jenkinsci/last-changes-plugin/blob/master/docker/plugins.txt#L27   Here's an image with the log of an execution: And here is the pipeline script I'm using:   pipeline { agent any stages { stage( 'Checkout' ) { steps { git 'https: //github.com/jenkinsci/last-changes-plugin.git' lastChanges since: 'LAST_SUCCESSFUL_BUILD' , format: 'SIDE' ,matching: 'LINE' } } } }

Rafael Pestano added a comment - 2018-01-25 22:59 I can see the error in jenkins logs although it doesn't interfere in job execution. I'll try do get ride of the error in logs.

Rafael Pestano added a comment - 2018-01-25 23:21 Can you try with attached last-jenkins.hpi?   last-changes.hpi
