Re: [lyo-dev] Fwd: Thread: [ERROR] No plugin found for prefix ’jetty’ in

[Didem Gurdur <didemgurdur@xxxxxxxxx>]

Dear Samuel,

Thank you very much for your reply.

I was using Run as > Maven build and received the message that I sent earlier.

Now I tried Run as> Maven install and received this error message:

                    </systemProperties>
                </configuration>
            </plugin>

and I changed it to the code you sent but I am still receiving same error message.

When I tried to Run> Maven install for org.eclipse.lyo.oslc4j.core

I received again message:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (default-testCompile) on project oslc4j-core: Compilation failure

What build command is failing? Run as -> Maven Install?

I haven't seen the error before, but you might want to try changing

    org.eclipse.lyo.oslc4j.registry/pom.xml

to use this jetty plugin instead of what's there

    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>9.1.5.v20140505</version>

If you try to build one of the projects individually (like
org.eclipse.lyo.oslc4j.core), does it work?
