If you upgraded TortoiseSVN lately you probably noticed that NetBeans / TortoiseSVN compatibility broke. This is because NetBeans at this time does not support the new Subversion 1.7 format. But it is fixable!
First of all, you need to specify the path to the svn.exe file provided by TortoiseSVN in NetBeans options window.
Next we must tell NetBeans to use the commanline executable by adding -J-DsvnClientAdapterFactory=commandline to the program shortcut.
In my case the NetBeans shortcut looks like:
"C:\Program Files\NetBeans 7.0.1\bin\netbeans.exe" -J-DsvnClientAdapterFactory=commandlineNow restart NetBeans and enjoy continued NetBeans TortoiseSVN compatibility.
