I've downloaded latest SVN and according to README.MD I was trying to build/package latest ExtJS SVN.
But running the command in the root of repo says:
C:\TFS\ExtJS>sencha.cmd ant -f extjs/build.xml -t .help
Sencha Cmd v18.104.22.1688
[ERR] Cannot find C:\TFS\ExtJS\tools\build\sencha-ant.xml imported from C:\TFS\ExtJS\extjs\build.xml
Where C:\TFS\ExtJS contains branch and is root of the repo.
Thanks for help.
