Question

While I try to create an android phonegap app I get the following error:
$ phonegap/lib/android/bin/create myapp
invalid option — ‘e’
Try `jar –help’ for more information

I am using Ubuntu 12.04

Answer 1

Jar was throwing this error because I was using the wrong jar (the sun sdk one)

I fixed this problem by simply running:

 $ sudo update-alternatives --config jar

and selecting oracles jar:

Selection    Path                                Priority   Status

  0            /usr/bin/fastjar                     100       auto mode
  1            /usr/bin/fastjar                     100       manual mode
* 2            /usr/lib/jvm/java-7-oracle/bin/jar   2         manual mode
