#195: java installation in macos

[mvomiero]

Fixes: #195

CAUSE of the issue:

• copying .ide.software.version to the target Path was failing.
  the problem was to my understanding and after my researches, that the source is a specific file path but the target is not recognized as a directory as it is, so when it tries to replace the target directory with the source file it fails.

SOLUTION:

• adding .ide.software.version to the target Path solves the problem.
• the file has to be copied just if it is a new installation, so it is possible to enclose it in a if statement that checks it's a new installation

COMMENTS:

• works fine for me, but
• still not super experienced about all the installation of commandlets. Would be nice if someone else could have a look.
