The required dependency should have been found at http://maven.xwiki.org/releases/org/xwiki/platform/xwiki-core-component/2.3.... but as you can see there's no jar there. The reason is that the xwiki-core-component module was split in multiple submodules. You need to edit you pom and change the dependency from xwiki-core-component to xwiki-core-component-api like this:
<dependency> <groupId>org.xwiki.platform</groupId> <artifactId>xwiki-core-component-api</artifactId> <version>${pom.version}</version> </dependency>
You're totally right. In fact, I just replace "xwiki-core-component" by "xwiki-core-component-api" and the build succeeded. So, I finally can have my jar ! Thanks.
Now, i'm facing that my component can't be caledl by groovy or velocity. I hope that you can help me again. My first thought was wondering if the component needs to be declared somewhere, but it seems not.
Yes it needs to be declared in a META-INF/components.txt file. See the doc at http://code.xwiki.org/xwiki/bin/view/Modules/ComponentModule Thanks -Vincent
Neither {{groovy wiki="false"}} def greeter = com.xpn.xwiki.web.Utils.getComponent(org.xwiki.essai.component.HelloWorld.class); println greeter.sayHello(); {{/groovy}} or {{velocity}} $greeter.sayHello(); {{/velocity}} works.
The groovy code throws the following error : org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Script Macro for content [def greeter = com.xpn.xwiki.web.Utils.getComponent(org.xwiki.essai.component.HelloWorld.class); println greeter.sayHello();] at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.evaluate(AbstractJSR223ScriptMacro.java:201) at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.evaluate(AbstractJSR223ScriptMacro.java:50) at org.xwiki.rendering.macro.script.AbstractScriptMacro.execute(AbstractScriptMacro.java:200) at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.execute(AbstractJSR223ScriptMacro.java:137) at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.execute(AbstractJSR223ScriptMacro.java:50) [...] at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:405) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:409) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) Caused by: javax.script.ScriptException: javax.script.ScriptException: java.lang.RuntimeException: Failed to load component [org.xwiki.essai.component.HelloWorld] for hint [default] at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:117) at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.eval(AbstractJSR223ScriptMacro.java:260) at org.xwiki.rendering.macro.script.AbstractJSR223ScriptMacro.evaluate(AbstractJSR223ScriptMacro.java:191) ... 79 more Caused by: javax.script.ScriptException: java.lang.RuntimeException: Failed to load component [org.xwiki.essai.component.HelloWorld] for hint [default] at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:317) at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:111) ... 81 more Caused by: java.lang.RuntimeException: Failed to load component [org.xwiki.essai.component.HelloWorld] for hint [default] at com.xpn.xwiki.web.Utils.getComponent(Utils.java:614) at com.xpn.xwiki.web.Utils.getComponent(Utils.java:635) at com.xpn.xwiki.web.Utils$getComponent.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:40) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:117) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125) at Script7.run(Script7.groovy:1) at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:314) ... 82 more Caused by: org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [org.xwiki.essai.component.HelloWorld] hint = [default]] at org.xwiki.component.embed.EmbeddableComponentManager.initialize(EmbeddableComponentManager.java:356) at org.xwiki.component.embed.EmbeddableComponentManager.lookup(EmbeddableComponentManager.java:109) at org.xwiki.component.internal.DefaultComponentManager.lookup(DefaultComponentManager.java:85) at com.xpn.xwiki.web.Utils.getComponent(Utils.java:612) ... 89 more
What is the descriptor for the component ? Besides, like I know the tutorial outdated, I tried to modify the code of the component by adding annotations and a components.txt, but the build failed cause the annotations was unknown (at least, they seems to be unknown).
Can anybody give me some ideas that I can use the HelloWorld component through velocity in my xwiki pages ? -- View this message in context: http://xwiki.475771.n2.nabble.com/Error-when-building-new-xwiki-component-tp...
