At any time, all the code in SVN should be compilable and should pass all the unit tests. There is no guarantee that it will be full featured - this is a work in progress.

Latest build

You can download the latest build from our Build server kindly hosted by Canoo AG.

Maven snapshot

Sonatype OSS repository hosts HtmlUnit snapshot, which is manually updated by the team once in a while. To use that, you can include the below in your POM:

            <name>Sonatype Nexus Snapshots</name>

Checking out SVN repository

Another way to get the latest code is through SVN. Create a directory for HtmlUnit (for instance c:\htmlunit or ~/htmlunit). Change to that directory and execute the following commands.

svn co .

Compiling the code

The preferred way to build HtmlUnit is with maven 3.

mvn compile

This will do an incremental compile of all the code.

mvn clean compile

This will do a clean compile of all the code.

Dependencies for IDE

Usually, you need to get the JARs for your IDE. You can do that by something like:

Eclipse: right click on the project -> Configure -> Convert to Maven Project

, alternatively:

mvn eclipse:eclipse


mvn idea:idea

This will create appropriate IDE project. Note that HtmlUnit is mostly at the bleeding edge, to the extent that an HtmlUnit-local repository has been created to store snapshots of various dependencies.

Running the tests

All the tests are based on JUnit.

mvn test

This will force a recompile of the java classes if needed.

mvn test -Dtest=DomNodeTest

This will run only the specified test class.

Tests currently assume that port 12345 is free on the machine, if you have Address already in use: JVM_Bind, then set the system property htmlunit.test.port e.g. -Dhtmlunit.test.port=10101.
Additionally class SocksProxyTest requires a SOCKS Proxy running at port 55555.


mvn package

In the project's target directory you'll able to see the generated jar file with the name "htmlunit-" followed by the version number.

mvn source:jar

This generates a source jar file.

mvn source:test-jar

This will generate a jar file of the test sources.

mvn org.apache.felix:maven-bundle-plugin:bundle

This will generate an OSGi bundle.

Forked Rhino (core-js)

You can get the source code from Maven central repository, while the repository resides in github.
