Plugin Development

[James Christian]

Hi, 

I want to develop a plugin in SCM-Manager, for that i have to store some values to repository, so in your context it'll be stored in repository.xml under <key><value> pair

But i dont know how to store and retrieve it with your Injection APIs

And I also want to create new XML files, like yours (e.g: repository.xml, users.xml)

So, i want to know how can i do that,

I already did learn what is Injection Dependency and what is Google Guice, but i really massed up with your APIs

Please Help me with this.

Hi,

You can get repositories from the RepositoryManager (https://docs.scm-manager.org/apidocs/latest/sonia/scm/repository/RepositoryManager.html). The RepositoryManager return Repository (https://docs.scm-manager.org/apidocs/latest/sonia/scm/repository/Repository.html) objects and you can fetch your key-value data from a repository with the getProperty method. Short example:

public class YourClass {

  @Inject

  public YourClass(RepositoryManager repositoryManager){

  Repository repository = repositoryManager.get("git", "yourgitrepository");

  String property = repository.getProperty("your-property");

  // do something with the property

  }

}

Storing configuration can be done with the Store API (https://docs.scm-manager.org/apidocs/latest/sonia/scm/store/package-summary.html). To store a single configuration file like users, repositories, etc you have to inject a StoreFactory (https://docs.scm-manager.org/apidocs/latest/sonia/scm/store/StoreFactory.html). From the factory you can retrieve a Store object (https://docs.scm-manager.org/apidocs/latest/sonia/scm/store/Store.html) which is able to store and load a JAXB (https://jaxb.java.net/guide/) class. Short example:

public class YourClass {

  private Store<YourConfig> store;

  @Inject

  public YourClass(StoreFactory storeFactory){

    // get the store from the factory

  store = storeFactory.get(YourConfig.class, "yours");

  }

  public void storeName(String name){

    YourConfig cfg = new YourConfig();

  cfg.setName("awesome name");

  store.set(cfg);

  }

}

@XmlRootElement

public class YourConfig {

  private String name;

  public void setName(String name){

    this.name = name;

  }

  public String getName(){

    return name;

  }

}

I hope this helps.

Thank u very much, i already did that and it works really well,

But i got another question,

Your SCM-MANAGER has jgit and svnkit ,entirely work on JAVA, but it doesn't have javahg, then how i m going to use hg functions into my plugin

I want to user repository specific features such as what are the changesets?, and what are the commits and its messages?

So how i can do that with your API?

Do i have to use SCM specific jar api, for example : to get changeset for git repository, do i have to use jgit.jar API?

and for svn also??

How do i work same with mercurial?, do i have to load javahg dependency into my plugin project?

Yo don't have to use repository type specific apis. There is a generic api which can be used to read svn,git and mercurial repositories. The main entry point for this api is RepositoryServiceFactory (https://docs.scm-manager.org/apidocs/latest/sonia/scm/repository/api/RepositoryServiceFactory.html). The javadoc of the service factory contains a simple example.

Sorry, i am asking a lot, but i can't use them, it has only little features, i want extra services such as push and pulll and commit,

and i tried with jGit, but at runtime it errors like classnotfoundexception : for jschException, but i already did that in maven

I tried other process like making classpath runtime, but it still cant access it,

I dont know how to do it, will you help me with it??

[Sebastian Sdorra]

The jsch library is excluded in the core of scm-manager. Are you defined a direct dependency for jsch?

Sebastian

[James Christian]

Yeah it is in core, but during plugin development it can't found, so i attached in classpath at your scm file and it worked.

I also mention you that i created one plug-in, how can i place in your plugin-market?

[Sebastian Sdorra]

I've to check you plugin before it can be uploaded to the plugin center. Is your plugin opensource? Could you send me an link to the repository?
