Re: "inspect tree" throwing java.lang.StringIndexOutOfBoundsException

[eugene yokota]

I was able to get normal output using sbt 0.12.1:

helloworld> inspect tree compile

[info] compile:compile = Task[sbt.inc.Analysis]

[info]   +-compile:compile::compile-inputs = Task[sbt.Compiler$Inputs]

[info]   | +-*/*:compile-order = Mixed

[info]   | +-compile:compile::streams = Task[sbt.std.TaskStreams[sbt.Init$ScopedKey[_ <: Any]]]

[info]   | | +-*/*:streams-manager = Task[sbt.std.Streams[sbt.Init$ScopedKey[_ <: Any]]]

[info]   | | 

....

Can you reproduce the issue with some publicly available build?

Just upgraded to SBT 0.12.1 because I wanted to use "inspect tree XXXX". It is throwing the exception listed below. Any suggestions for avoiding the problem?

Just did a little bit of debugging on this and the problem is that in SettingGraph.scala for dump terminals (TERM=dump, e.g. the Emacs shell) JLine.usingTerminal(_.getTerminalWidth) returns 0, which creates the stack trace below. Use a different terminal (e.g. Emacs terminal) and you should be fine. - RT
