Description

Our Jenkins server is running jenkins-2.9-1.1. Git plugin 2.5.2 is installed.

I have a Jenkins job that I use to get the changelog of our GIT repos.

In the job's Source Code Management section, I selected multiple SCMs. I added 4 GIT repos (horizon, keystone, glance & base). In each GIT section, I added the GIT repo info (repo URL, credentials, branches to build).

For Additional Behaviors, I added

Calculate changelog against a specific branch

Check out to a sub-directory

Custom SCM name

E.g.



  • Branch to build refs/heads/next

  • Calculate changelog against a specific branch

    Name of repository: refs

    Name of branch: tags/

Issue:

If I ran the job with just 1 GIT repo, it would return the changelog.

If I included just 3 of the 4 repos (when run individually or together in the same job), it would return the changelog for each repo.

If I included all 4 repos, no changelog would return.

So, it looked like 1 of these 4 repos (openstack-base in this case) couldn't get the changelog.

What I found out:

In the build dir, I could see the changelog.xml file. It contained all the changelog of all 4 repos.







The problem is that when I added all 4 repos to the job, it should return the changelog of

3 repos, but the job returned no changelog for all 4. Not even the 3 repos that suppose to return something when ran individually or together. It looked like the one job that has changelog issue (openstack-base) caused the other 3 to not report the changelogs also.

I went to the Jenkins log (/var/log/jenkins/jenkins.log) and it complained about the changelog having an invalid XML character:

It looked like those ^ &, etc. char are invalid xml characters. There are other lines with these invalid char also.

We could write a script to remove those "invalid characters" after the job is finished, but how do we display the changelog the same way we see them in the job build?

What is the best way to get the GIT plugin to clean up/remove/ignore those invalid char when calculating the changelog so that when the job is done, it will display the changelog properly without having to run additional tasks to "cleanup"/fix the problem?

I have a Jenkins job that I use to get the changelog of our GIT repos.



In the job's Source Code Management section, I selected multiple SCMs.  I added 4 GIT repos (horizon, keystone, glance & base). In each GIT section, I added the GIT repo info (repo URL, credentials, branches to build).
