[isabelle-dev] isabelle build glitch

[Lars Noschinski]

Hi!

Today, I updated to Isabelle 4de92b4aa74a. Then I did

--------------------------------------------------------------------------
$ isa build -b -d ~/P/afp/thys/ Simpl
### Building Isabelle/Scala ...
Changed files:
   General/pretty.scala
   System/build.scala
   System/options.scala
rm: Entfernen von „classes/isabelle“ nicht möglich: Das Verzeichnis ist 
nicht leer
--------------------------------------------------------------------------

I wondered about the error message, aborted with Ctrl-C and tried again:

--------------------------------------------------------------------------
$ isa build -b -d ~/P/afp/thys/ Simpl

I deleted and reverted $ISABELLE_HOME/lib. Now everything seems to work 
again. As a data point: While executing the first "isa build", another 
instance of this Isabelle instance was running.
