Can you please share the download url.

** Still have the same problem :pensive:**

Make sure that you have restarted the terminal. If it still shows the same error, try building with the -r flag, this will invalidate the caches and build the extension afresh.

After rush build -r

:slightly_frowning_face: :slightly_frowning_face:

It looks like for some reason, Rush is still picking JDK 18 to compile your source files. Are you sure you restarted your terminal? If yes, can you try restarting your computer and then building with the -r flag again?

Now only show build faild

It’s most likely that your Java installation doesn’t have a JDK (even if the folder says otherwise). Try running javac -version in terminal to confirm this, if it says program not found then you don’t have JDK installed.

You can re-download the correct JDK installer from the link posted earlier in this topic, or try this:

The name of you extension’s class should be same as the name used while creating the project using the create command. Change the class name from Vsrollhandler to Alfi to get rid of the errors.

If you wish to change the name of your extension, delete all the files inside of the .rush folder of your project and change the value of name field in rush.yml to desired name.

I make 2 clss Alfi and Vsrollhandler in Alfi pack age Java class on Alfi class succes compile and Vsrollhandler error’. Is any way make 2clas in one package

Yes, it’s possible. But you can not make multi components extension in Rush so you can only use those annotations in your main defined class. For ex, if you move your all blocks from Vscrollhandler to your main defined class (Alfi) or declare your Vscrollhandler as the main class as Shreyash mentioned then you would not see above errors.

I So only one main class can not create two main classes…

Status update 2 – I spent the last month laying the foundation of the new update, implementing a few new features, and mostly, refactoring the horrible spaghetti only God knows which drunk head wrote (no, don’t look at me).

We now have a mostly working dependency management system in place, written entirely from scratch to best meet Rush’s needs. Along with that I recently added support for the helper blocks. The multi-component extensions are also supported now.

Talking about beta testing, I will certainly start it in a couple of days. I wanted to start it by the end of the last month, but things were mostly half-baked and/or broken and it didn’t really made any sense to beta-test at that phase. If you’re interested in beta testing Rush, PM me here on the community or on Discord (my username: shreyash#4002).

Also, if you have any feature requests, suggestions, or bug reports, now is the right time to let me know about them. Bring them on!

Before we finish, here’s a peek at a handy little feature I implemented to view the dependency tree of your extension project. This screenshot is from my media-notification extension.

how write permission in rush??
fill this example

<?xml version="1.0" encoding="utf-8"?>
<!-- <activity android:name=".MainActivity">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity> -->

This is how you declare permissions in the Android manifest:

<manifest ...>
    <uses-permission android:name="android.permission.CAMERA"/>
    <application ...>
        ...
    </application>
</manifest>

Read more about declaring permissions here:

iam still not understand can you show full exampel in rush permission
