   ## JIRA
   [SCM-1028](https://issues.apache.org/jira/browse/SCM-1028) Vulnerability: 
Clear text password is logged by JGit provider and by gitexe remoteinfo on a 
ls-remote failure
   
   ## Changes
   - GitUtil.java:
     - add method encodeURIComponent(String s) to provide a central common 
encoding for user credentials within URLs
     - add method maskPasswordInUrl(String urlWithCredentials)
       - implementation taken from AnonymousCommandLine.java
       - improve regex pattern to be more precise
       - replace wrapped with delimiters ':' and '@' to avoid replacing the 
password within probable other places of the URL to avoid password guessing by 
using e.g. redundant URL parameters
   
   - AnonymousCommandLine.java:
     - move current password masking implementation to GitUtil
     - use implementation from GitUtil
   
   - GitScmProviderRepository.java:
     - add method getFetchUrlWithMaskedPassword()
     - add method getPushUrlWithMaskedPassword()
     - method getUrl(RepositoryUrl repoUrl):
       - use user name and password encoding from 
GitUtil.encodeURIComponent(String s)
     - toString():
       - 👉 **BREAKING** change: provide URL content with masked password to 
reduce risk of usage within logs or exceptions with showing passwords by that
   
   - JGitUtils.java:
     - method prepareSession(Git git, GitScmProviderRepository repository):
       - log using methods:
         - GitScmProviderRepository.getFetchUrlWithMaskedPassword()
         - GitScmProviderRepository.getPushUrlWithMaskedPassword()
   
   - GitRemoteInfoCommand.java:
     - use GitScmProviderRepository.getFetchUrlWithMaskedPassword() for 
exception message
   
   - Update JUnit tests accordingly:
     - GitScmProviderRepositoryTest.java
     - GitCommandLineUtilsTest.java
   
   ## Test result
   - All JUnit tests passed

> *Issue(s):*
>  # {*}JGit provider{*}: If the git password contains special characters which 
> are differently encoded by the {{URI class}} than {{{}by 
> URLEncode.encode{}}}, then the password masking does not become effective and 
> the password is logged in clear URI encoded format by the jgit provider.
>  # {*}Gitexe remoteinfo{*}: In case ls-remote is failing, then a 
> {{ScmException}} is being thrown with the fetch URL passed as error message 
> containing the URI encoded clear password.
> *Root cause(s):*
>  # The URL encoding used for the credentials within fetch and push URL 
> differs from the encoding being used for masking the password at
