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.
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);

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Besides, like I know the tutorial outdated, I tried to modify the code of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 ?
