Hello! I have a Jenkins build for MaterialDesignLite and the Pharo 7 build never end. I load the code via the command line "eval" with the "--save" parameter and a Metacello command. While adding some log I found the problem. It comes from this method: EvaluateCommandLineHandler>>evaluate: aStream | result | [ result := Smalltalk compiler evaluate: aStream. self hasSessionChanged ifFalse: [ self stdout print: result; lf ] ] on: Error do: [ :error | self handleError: error ] In Pharo 6 it ends perfectly. In Pharo 7 there is an error and we end up in the catch. Here is the stack I could isolate: MessageNotUnderstood(Exception)>>signal UndefinedObject(Object)>>doesNotUnderstand: #'>=' AnObsoleteZnCrPortableWriteStream(WriteStream)>>nextPut: [ :v | self nextPut: v ] in AnObsoleteZnCrPortableWriteStream(Stream)>>nextPutAll: ByteSymbol(SequenceableCollection)>>do: AnObsoleteZnCrPortableWriteStream(Stream)>>nextPutAll: AnObsoleteZnCrPortableWriteStream(WriteStream)>>nextPutAll: MultiByteFileStream(StandardFileStream)>>printOn: AnObsoleteZnCrPortableWriteStream(Stream)>>print: VTermOutputDriver>>print: I have no idea how to correct this and it's pretty late now. Maybe someone will know :) https://pharo.fogbugz.com/f/cases/21566/EvaluateCommandLineHandler-is-broken... -- Cyril Ferlicot https://ferlicot.fr
