Question

After cloning the ringojs repository, i run in the directory:

ant jar

However, the build is failed with around 100 errors, here is some of them:

    init:

    compile:
        [javac] Compiling 55 source files to /Users/ZConsulting/repos/ringojs/build/classes
        [javac] repos/ringojs/src/org/ringojs/engine/Callback.java:19: error: package org.mozilla.javascript does not exist
        [javac] import org.mozilla.javascript.Context;
        [javac]                              ^
        [javac] repos/ringojs/src/org/ringojs/engine/Callback.java:20: error: package org.mozilla.javascript does not exist

        [javac] import org.mozilla.javascript.Context;
        [javac]                              ^

BUILD FAILED
repos/ringojs/build.xml:76: Compile failed; see the compiler error output for details.

My context is building back end application on googleappengine for my project.

Answer 1

You will need apache ant and ivy installed. Ivy should download the rhino jar.

If ivy and ant are insalled do a

ant update
ant jar

This should help.
