Error running maven with settings file when running multibranch pipeline with a slash in the branch

      Description

      I configured a maven settings and global settings file in the Pipeline Maven Configuration of the folder containing the multibranch pipeline job.  When I run the following stage from my Jenkins file:

      stage('Package') { 
 steps {
  withMaven()  { 
   bat "mvn clean package"
  }
 }
}

      I get this error:

      [ERROR] Error executing Maven. [ERROR] The specified user settings file does not exist: C:\jenkins\dctl\branchespackageFspring-boot\workspace@tmp\withMaven22e2d518\settings.xml

      The reason I get this error is that the folder containing the branch is called branches%2Fspring-boot and the config file provider is replacing %2 with package (I assume this is because package is the second argument to the script that is invoked)

          I did and the problem is that when the with maven wrapper script is created, the pathnames contain %2F which when invoked inside the wrapper scripts get evaluated as arguments.  Here is the log output from WithMavenStepExecution2:

           

          Generated Maven wrapper script: 
@echo off
echo ----- withMaven Wrapper script -----
"C:\APPS\apache-maven-3.6.0\bin\mvn.cmd" --batch-mode --show-version --settings "e:\cc-build\checkout\abc\citest\branches%2Ftest\workspace@tmp\withMaven94865076\settings.xml" --global-settings "e:\cc-build\checkout\abc\citest\branches%2Ftest\workspace@tmp\withMaven94865076\globalSettings.xml"  %*

          when calling maven in that manner, it will not work.  The generated wrapper script should double the % signs in each path argument.  For example:

           

           

          @echo off
echo ----- withMaven Wrapper script -----
"C:\APPS\apache-maven-3.6.0\bin\mvn.cmd" --batch-mode --show-version --settings "e:\cc-build\checkout\aws\citest\branches%%2Ftest\workspace@tmp\withMaven94865076\settings.xml" --global-settings "e:\cc-build\checkout\aws\citest\branches%%2Ftest\workspace@tmp\withMaven94865076\globalSettings.xml"  %*

           I tested modifying the withMaven wrapper script manually and it works.

          From what I understand the code, the method setupMaven which defines and overrides the MAVEN_CONFIG environment variable is not Windows specific so that making the change in that method would require knowing the platform.
