Description ebaumann 2014-01-05 13:31:58 UTC 
This happens when developing the same project on different operating systems with different line separators. If a project.properties file was created under Windows, the line ends are CRLF according to http://wiki.netbeans.org/FaqEditorEOLs. If the project is opend under Linux, the line endings will be converted *automatically* to LF regardless whether the project.properties file is opend in an editor or not. The CRC in project.xml may be changed too.

Reproduce:

* Create an Ant based project under Windows or Linux
* Use a version control system for that project, e. g. Mercurial
* Edit the project.properties e.g. adding a source reference to a JAR library
* Commit the changes
* Open that project under the opposite operating system (Linux or Windows
  - use an operating system with a different line separator)
* The version control system displays, that the project.properties has been 
  changed. The diff view does not show the changes because the line separator
  is invisible, but they can viewed in a hex editor or the plugin that shows
  the operating system line separators. After a revert on the VCS the
  hex editor shows the line separators of the other operating system
Comment 1 Milos Kleint 2014-01-15 12:33:16 UTC 
version controls should be able to always checkout the sources on the given platform with given new lines (thus not ending up with Win newlines on unit machine)

Comment 2 ebaumann 2014-01-15 14:30:01 UTC 
This is a workaround. If only one person in a probably huge developer community does not configure his VCS to a given line separator, you have this annoyance. In the reality everything what can go wrong will go wrong.

Since there is no need for NetBeans to transform existing line endings in configuration files automatically, this behaviour should be changed. In previous versions NetBeans worked as expected.
Comment 3 Milos Kleint 2014-01-15 14:52:03 UTC 
do you know what versions? 7.3 worked ok?
Comment 4 ebaumann 2014-01-15 14:59:35 UTC 
I think, 7.3 was ok.
