leinigen 1.7.1 stalled when used from Jenkins

[Pierre Allix]

Hello,

I have a build script called from Jenkins that calls "lein clean". Unfortunately lein stalled when executed from the script whereas it works fine if I do executed it from the command line.

Leiningen is stalled executing this command:

java -Xbootclasspath/a:/home/jboss/.m2/repository/org/clojure/clojure/1.2.1/clojure-1.2.1.jar -client -XX:+TieredCompilation -Dleiningen.original.pwd=/home/jboss/.jenkins/workspace/Carneades/src/CarneadesEngine -Dleiningen.trampoline-file=/tmp/lein-trampoline-2614 -cp :::::test/:src/:resources/:/home/jboss/.lein/self-installs/leiningen-1.7.1-standalone.jar jline.ConsoleRunner clojure.main -e (use 'leiningen.core)(-main) /dev/null clean

Strace shows this error:

strace -p 2640

Process 2640 attached - interrupt to quit

--- SIGTTOU (Stopped (tty output)) @ 0 (0) ---

futex(0xb6cf4bd8, FUTEX_WAIT, 2641, NULLp^C <unfinished ...>

and trying to execute the command from the command line shows this stacktrace  (but here i'm not sure that my escaping of parenthesis and quote with backslashes is correct)

java -Xbootclasspath/a:/home/jboss/.m2/repository/org/clojure/clojure/1.2.1/clojure-1.2.1.jar -client -XX:+TieredCompilation -Dleiningen.original.pwd=/home/jboss/.jenkins/workspace/Carneades/src/CarneadesEngine -Dleiningen.trampoline-file=/tmp/lein-trampoline-27012 -cp :::::test/:src/:resources/:/home/jboss/.lein/self-installs/leiningen-1.7.1-standalone.jar jline.ConsoleRunner clojure.main -e \(use \'leiningen.core\)\(\-main\) help

Any ideas?

I found the error.

Somehow it was caused by Jenkins started as standalone JAR by the nohup command but nonetheless not properly being "daemonized".
