problem in packaging jenkins plugin tutorial

[Punit Jain]

so basically i am trying to build a plugin jenkins, and for that i am trying to packaging the code from the jenkins plugin tutorial
https://wiki.jenkins-ci.org/display/JENKINS/Plugin+tutorial#Plugintutorial-CreatingaNewPlugin
but when i am firing command mvn package, it's not downloading some of dependencies.
here is the stack trace:

can anybody please tell me, what is going wrong.

[Peter Johnson]

I check the URLs in the download message and the JAR file do appear there. Do you perhaps need to configure a proxy? Also, try accessing the JARs from a browser using the URLs in the download statements.

[Punit Jain]

yes, i am not able to access few links:
http://repo.jenkins-ci.org/public/org/jenkins-ci/main/jenkins-test-
http://repo.jenkins-ci.org/public/org/jenkins-ci/main/jenkins-war/1
http://repo.jenkins-ci.org/public/org/jenkins-ci/main/jenkins-war/1

and i am able to access these links:

http://repo.jenkins-ci.org/public/org/jenkins-ci/plugins/subversion
http://repo.jenkins-ci.org/public/org/jenkins-ci/main/jenkins-core/
http://repo.jenkins-ci.org/public/org/jenkins-ci/plugins/subversion/

do i need to create proxies for all above links?
i mean in host element of proxy settings, do i need to give above url's?

also i havn't stared jenkins server when packaging this projects?
also do i need to start tomcat as my servce for this?

Thanks.

[Peter Johnson]

You might try using the full URL and not just the part the first on the first line; didn't you notice that they all wrapped to a second line???

You don't need to run Tomcat or Jenkins to build a Jenkins plugin.

[Punit Jain]

okay, so i have created two proxies:

<proxies> <proxy> <id>optional</id> <active>true</active> <protocol>http</protocol> <username>proxyuser</username> <password>proxypass</password> <host>http://repo.jenkins-ci.org/public/org/jenkins-ci/main</host> <port>80</port> <nonProxyHosts>local.net|some.host.com</nonProxyHosts> </proxy> <proxy> <id>optional</id> <active>true</active> <protocol>http</protocol> <username>proxyuser</username> <password>proxypass</password> <host>http://repo.maven.apache.org/maven2/org/jenkins-ci/main</host> <port>80</port> <nonProxyHosts>local.net|some.host.com</nonProxyHosts> </proxy> </proxies>

but still getting this error:

[Punit Jain]

it works for me now.
i don't know, what was the problem, but i again tried all the steps in my office and it worked, slow internet connection might be a reason but i am not quite sure.
okay so, after packaging that project i installed eclipse maven plugin, and import that project.
in pom.xml i got one error, can anyone help me with this error?

Multiple annotations found at this line:
	- Plugin execution not covered by lifecycle configuration: org.jenkins-ci.tools:maven-hpi-plugin:1.74:insert-test (execution: default-insert-test, phase: generate-test-sources)

	- Plugin execution not covered by lifecycle configuration: org.jvnet.localizer:maven-localizer-plugin:1.13:generate (execution: default, phase: generate-sources)

Next, the tutorial says,

Let's take a look at the source code. A plugin's main entry point is a PluginImpl class that extends from Plugin. Once Jenkins detects your plugin class (via its inheritance relationship from Plugin), it will create an instance, and invoke methods. A Plugin class is optional; a plugin may simply implement extensions:

Most of the time, a plugin class just registers extension points, and your main work involves implementing those extension points. See the source code for more about how a Builder is implemented and what it does.

i didn't found any PluginImpl class in the project.

Next, i set this property set MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n and run command mvn hpi:run
but don't know what it do?

Next i open browser and open http://localhost:8080/
i got this below screen:

now i am confused how do i start writing and test the code.
can anyone please guide me here or any sample plugin?

Thanks

[Peter Johnson]

This should help: http://wiki.eclipse.org/M2E_plugin_execution_not_covered

The MAVEN_OPTS you posted let you remotely connect to the JVM running the code (which I will assume is Jenkins).
