strace’ing a Clojure process under lein
Today I wanted to strace a JVM subprocess and then exits, and I discovered a minor roadblock: It was a Clojure program being run using the Leiningen build tool. lein run
strace profile to ~/.lein/profiles.clj to call that instead of java directly. If you don't have any profiles already, the file might end up looking like this:
#!/bin/bash
strace -f -o lein-strace.out in the current directory and see what turned up!Thanks to ridcully in the #clojure IRC channel on freenode for reminding me to use the -f option (trace forked subprocesses too!)
