# BUILDING JSIEVE WITH MAVEN
#############################################################################

1) Install maven 2.0.9

2) Add maven to your path and make sure you also have a JAVA_HOME environment
   variable to point a java 1.4+ virtual machine.

3) Run "mvn package"

# BUILDING JSIEVE WITH ANT
#############################################################################

The source trunk for JSIEVE no longer includes Ant, so in order to
build JSIEVE, you will need to install Ant as well as acquire JSIEVE
source from subversion or a source tarball.

JSIEVE uses JavaCC during the build process to generate the script parser.
Unfortunately, though the latest codebase is now available under the BSD
license there is (at this time) no official open sourced release. So
to build JSIEVE download the JavaCC 4.0 release from 
https://javacc.dev.java.net/. Extract the javacc.jar and copy into the
root of the JSIEVE directory. Rename this to javacc-4.0.jar.

You also have to download activation-1.1.1.jar and mail-1.4.1.jar files to 
the root folder in order to build/run unit tests.

Steps:

1) Install Ant (v1.6.5 as of the time of this writing)

2) Add Ant to your path.  For me, I do the following:
   $ tar zxvf apache-ant-1.6.5-bin.tar.gz
   $ mv apache-ant-1.6.5 /usr/local
   $ ln -sf /usr/local/apache-ant-1.6.5 /usr/local/ant
   $ ln -sf /usr/local/ant/bin/ant /usr/local/bin/ant

3) Change any JSIEVE-related build scripts that you might have to call
    Ant directly, e.g.:  ./build.sh <target> ==> ant <target>

That's it.  Please contact general@james.apache.org if you have any
problems.
