body: <p>when I am trying start STS (Spring Tool Suite) I am getting this error:</p>

  !MESSAGE Warning: EGit couldn't detect the installation path "gitPrefix" of native Git. Hence EGit can't respect system level
  Git settings which might be configured in ${gitPrefix}/etc/gitconfig under the native Git installation directory.
  The most important of these settings is core.autocrlf. Git for Windows by default sets this parameter to true in
  this system level configuration. The Git installation location can be configured on the
  Team &gt; Git &gt; Configuration preference page's 'System Settings' tab.
  This warning can be switched off on the Team &gt; Git &gt; Confirmations and Warnings preference page.
  
  !ENTRY org.eclipse.egit.ui 2 0 2014-08-12 09:05:15.348
  !MESSAGE Warning: The environment variable HOME is not set. The following directory will be used to store the Git
  user global configuration and to define the default location to store repositories: 'C:\Users\Geek Labs'. If this is
  not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
  EGit might behave differently since they see different configuration options.
  This warning can be switched off on the Team &gt; Git &gt; Confirmations and Warnings preference page.
