Modify Content Security Policy

Ref: https://content-security-policy.com/ and https://wiki.jenkins-ci.org/display/JENKINS/Configuring+Content+Security+Policy

Jenkins URL (Azure VM) : https://build-hee.transformcloud.net/jenkins/script

System.setProperty(hudson.model.DirectoryBrowserSupport.class.getName() + ".CSP", "script-src 'unsafe-inline' 'self';")
System.setProperty("jenkins.model.DirectoryBrowserSupport.CSP", "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline';")

To persist the security changes the following command can be executed from the command line :

$ java -Dhudson.model.DirectoryBrowserSupport.CSP="sandbox allow-scripts; default-src 'self'; script-src * 'unsafe-eval'; img-src *; style-src * 'unsafe-inline'; font-src *" -jar jenkins.war

NOTE : The web browser refresh does not always reload the page with the new relaxed rules due to caching. To ensure this doesn't happen it's advised to restart your browser.

If this needs to be reset to default (more secure) the run the following command :

System.clearProperty("hudson.model.DirectoryBrowserSupport.CSP")
