ESAPI is easy to build yourself using Git and Maven. Ensure that you are using UTF-8 for all source code.

$ git clone git@github.com:ESAPI/esapi-java-legacy.git    # This will clone the 'develop' branch.
$ cd esapi-java-legacy
$ mvn -Dmaven.test.skip=true package  # Build ESAPI. Omit the '-D' argument if you wish to run tests.

Maven will generate a "target" directory that contains the ESAPI jar file. This will allow you to use it locally from other Maven projects.

To generate project reports use:

$ mvn site

Then, point your browser to the file "target/site/index.html". Note that this will also include the ESAPI Javadoc, under "target/site/apidocs".
