Jenkins java.nio.charset.UnmappableCharacterException: Input length = 1

Question

I am working on a Jenkins application and pipeline to test and deploy Apex Code from a Bitbucket repository to Salesforce. So far I've managed to communicate my repository with my Jenkins environment. My Jenkins instance is running on Windows 10 in my company laptop, and I've reached the final steps in this guide: https://medium.com/@r.kurchenko/setup-continuous-integration-based-on-salesforcedx-c9f461c4db03

The problem I'm trying to deal with right now is that on a push to my repository, although the pipeline starts it doesn't even get to the build step and gives me the following error message:

Initially, I thought it might be a permission error, as I am not the laptop's administrator, and the home directory of my Jenkins Instance was inside my user files, but after changing the directory to somewhere else I still get the same error. I figured it might be the java.nio.charset.UnmappableCharacterException: Input length = 1 exception but, after researching it thoroughly, I cannot figure out where in Jenkins' pull operation this is executed and whether there is a way for me to solve it.

I would greatly appreciate any leads or information on what could be causing this issue.

Answer 1

I solved the problem by setting the language for non-Unicode programs: In Start -> Settings -> Time & Language -> Language -> Administrative language settings. Administrative tab. Screenshot here

Answer 2

If you run Jenkins on windows. I solved the problem by

1. add System Environment Variable
   • KEY JAVA_TOOL_OPTIONS
   • VALUE -Dfile.encoding=UTF8
2. restart system
3. test build

Because on Jenkins 2.361.1 (LTS). It read jenkinsfile by using system default Encoding (Windows = x-windows-874)

Answer 3

Add -Dfile.encoding=UTF-8 to your jenkins.xml Example:

<arguments>-Xrs -Xss4096k -Xmx2048m -XX:MaxPermSize=512m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -Dfile.encoding=UTF-8</arguments>
