This is a java wrapper around the fabulous tool by Douglas Crockford, jslint (See http://jslint.com/). It provides a simple interface for detecting potential problems in JavaScript code.

You can run it on the command line:

% java -jar jslint4java-${project.version}.jar application.js
jslint:application.js:11:9:Line breaking error ')'.
jslint:application.js:11:10:Missing semicolon.

There are a multitude of options; try --help for more details.

The output is colon separated fields. The fields are:

• "jslint"
• the file name
• the line number (starting at zero)
• the character number (starting at zero)
• the problem that was found

You may also use the jar as an ant task. The quickest way to get started is to drop it in ~/.ant/lib. See docs/ant.html for more details.

NB: The packaged jar file includes a builtin version of rhino (a JavaScript engine). If this causes trouble, you can download a standalone version through the maven repository.

If you wish to use jslint4java from within Java, please use a maven dependency:

<dependency>
  <groupId>com.googlecode.jslint4java</groupId>
  <artifactId>jslint4java</artifactId>
  <version>${project.version}</version>
</dependency>
