the problem is in the deploypath attribute of the module.xml file If in the file DeployPath="${cspdir}" ... <CSPApplication CookiePath="/appl/" DefaultTimeout="900" DeployPath="${cspdir}" Description="CSV Anonymizer Application" MatchRoles=":%All" PasswordAuthEnabled="0" Recurse="1" ServeFiles="1" ServeFilesTimeout="3600" UnauthenticatedEnabled="1" Url="/appl" UseSessionCookie="2"/>
Installing cleans up the csp directory. The system portal is broken.
There should be restrictions on DeployPath to avoid this outcome.
#278 is related, as part of the best-practice alternative - just reference the package install directory instead.
