Jerome Lacoste commented on MNG-463:
------------------------------------
Yes. m2-bootstrap-all.sh
The code that performs the delete is I think in MBoot.java
[...]
File dist = new File( mavenHome );
System.out.println( "Maven installation directory: " + dist );
[...]
// build the installation
FileUtils.deleteDirectory( dist );
[...]
> [data loss] installation script inconditionally deletes M2_HOME contents

> I've set up M2_HOME to a wrong directory by mistake, and the m2 installer
> deleted everything in it...
> May I suggest to use the same strategy used by the cargo installer?
> I.e.
> if (target directory empty || m2 marker file exists)
> - copy the contents
> - add a marker file specific to m2
> else
> warn user
> See CARGO-27 for the original CARGO issue.
