GroovyでHTTPBuilderをGrabしようとしたらエラー

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.1' )
 
def http = new groovyx.net.http.HTTPBuilder('http://www.codehaus.org')

と実行すると

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during conversion: Error grabbing Grapes -- [download failed: commons-codec#commons-codec;1.3!commons-codec.jar, download failed: xerces#xercesImpl;2.8.1!xercesImpl.jar, download failed: xml-apis#xml-apis;1.3.03!xml-apis.jar]

となり、エラー。
次はGrapeコマンドでhttp-builderのインストールを試みる。

grape install org.codehaus.groovy.modules.http-builder http-builder 0.5.2

これもエラー

なんだかMavenのローカルリポジトリにそれぞれのjarが無いとかで怒られてる感じ。

無いと言われたjarを落として、然るべき場所に配置して、もう一回Grapeコマンド。
jarを落とす時に"mvn install hogehoge"みたいな感じで落としたかったけど、やり方わからなかったので、手動で落として配置。

$ Grape install org.codehaus.groovy.modules.http-builder http-builder 0.5.2

上手く行ったようだ。

んで、元のコード動かしたら特にエラーも出ずに動いてくれた。

GroovyやGradleだとMavenから逃れられると思ってたけど、そうも行かないようだ。
