Project Archive and JAR

The latest JAR can be obtained from the Codehaus Maven repository. The repository also contains project assemblies (.tar.gz), which include the source code, generated JavaDoc, and dependency JARs. The latest release is version 0.7.2.

Older releases may also be found under the old group ID.

Maven Users

Maven users can simply copy the dependency tag into their own project:


You might also need to add the Codehaus repository to your project POM as well:


Using Grape

Grape is a neat dependency management feature in Groovy 1.6+ that allows you to download and add JARs to your classpath at runtime.

You can automatically put HTTPBuilder in your classpath by using the following annotation on a method in your code:

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7' )

def http = new'')
// ....

Note that in Groovy 1.6, the @Grab annotation must occur on a method definition (it can be an empty method.) Putting the annotation before a statement such as a variable declaration will not work. This is a common error and Grape will not provide any indication that it is not augmenting the runtime classpath. This should change in Groovy 1.7.

If you are still having problems, try calling grape from the command line like so:

$ grape resolve org.codehaus.groovy.modules.http-builder http-builder 0.7.2
  # will tell you where grape is looking and give detailed config information

$ grape install org.codehaus.groovy.modules.http-builder http-builder 0.7.2
  # will attempt to download the JAR and transitive dependencies

The above commands will tell you which repository URLs grape is trying to download from if it cannot find the artifact.

If you are trying to use a snapshot version of HTTPBuilder, you might also need to create the following file in ~/.groovy/grapeConfig.xml:

<?xml version="1.0" encoding="utf-8"?>
  <settings defaultResolver="downloadGrapes" />
    <chain name="downloadGrapes">
      <filesystem name="cachedGrapes">
        <ivy pattern="${user.home}/.groovy/grapes/[organisation]/[module]/ivy-[revision].xml" />
        <artifact pattern="${user.home}/.groovy/grapes/[organisation]/[module]/[type]s/[artifact]-[revision].[ext]" />
      <ibiblio name="codehaus" root="" m2compatible="true" />
      <ibiblio name="codehaus.snapshots" root="" m2compatible="true" />
      <ibiblio name="ibiblio" m2compatible="true" />
      <ibiblio name="java.net2" root="" m2compatible="true" />

Note the codehaus.snapshots line, which tells Grape where HTTPBuilder's snapshot builds are located, since that repository is not searched by default.
