HttpUnit imports not found in Eclipse

Question

I'm trying to get started with HttpUnit. I made an Eclipse project with a simple example, but there seems to be a neverending stream of unresolved dependencies and imports it can't find. So I'm starting over:

I just want to get this tutorial to work: http://www.httpunit.org/doc/tutorial/

My jars folder contains:

activation-1.1.jar
js-1.6R5.jar
jtidy-4aug2000r7-dev.jar
junit-3.8.1.jar
mail-1.4.jar
nekohtml-0.9.5.jar
servlet-api-2.4.jar
xercesImpl-2.6.1.jar
xmlParserAPIs-2.6.1.jar

My .classpath file says:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="src" path="jars"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

Why can't the following imports be resolved?

import com.meterware.httpunit.*;
import com.meterware.servletunit.*;
import junit.framework.*;

Thanks

Answer 1

In the Package Explorer or Project Explorer view select all JARs, right-click and choose Build Path > Add to Build Path.

If you did that, the .classpath file should have an entry like <classpathentry kind="lib" path="... .jar"/> for each .jar file.

As one of the httpunit committers I'd recommend to use the maven dependency.

The M2Eclipse plugin will help you to use maven:

https://www.eclipse.org/m2e/

as of 2018-09 you can use the version 1.7.3 dependency for httpunit. Then all other depencencies are automatically resolved.

<!-- https://mvnrepository.com/artifact/org.httpunit/httpunit -->
<dependency>
    <groupId>org.httpunit</groupId>
    <artifactId>httpunit</artifactId>
    <version>1.7.3</version>
    <scope>test</scope>
</dependency>

at https://mvnrepository.com/artifact/org.httpunit/httpunit you'lll aways find the latest release.

If you'd like to find out httpunit's own dependencies you can run:
