How do you add classpath on IntelliJ IDEA

Mohamed_Abdelbasset · August 9, 2024, 7:55pm

hello
i am a newbee and i want your help, i want to configure my intellij FOR editing java extensions...
my question is how i can do for this kind of imports :

import com.google.appinventor.components.common.ComponentCategory;
import com.google.appinventor.components.runtime.AndroidNonvisibleComponent;
import com.google.appinventor.components.runtime.ComponentContainer;
import com.google.appinventor.components.runtime.Notifier;
import com.google.appinventor.components.runtime.EventDispatcher;
import com.google.appinventor.components.annotations.SimpleProperty;
import com.google.appinventor.components.common.PropertyTypeConstants;
import com.google.appinventor.components.annotations.UsesLibraries;
import com.google.appinventor.components.annotations.UsesPermissions;

where i can download this libs ? and how i import them

thank you

Please let us know which build tool you're using to build extension? So we might help you better.

no need to download any external lib
just put this imports in your .java file after packj
eg..
packaj com.myapp

import.....
import...........

Tip

you can also use 1 import to do this
import com.google.appinventor.components.*;

i am using intelliJ IDEA IDE .
can this intelliJ build extensions .aix ? any idea ? netbeans ?
wht is the best ide to do this ?

thx

JEWEL · August 10, 2024, 12:05pm

I'm not talking about the IDE, it's about the build tool. Are you using the App Inventor Open Source program to build aix or the Extension Template Repository? Let me know it so I can help you more.

Mohamed_Abdelbasset · August 10, 2024, 12:11pm

ah sorry ... yes i am using the App Inventor Open Source. (ant extensions).
but i i am editing the java file with intellij and i want that intellij do the autocompletion for all methods for this imports .

JEWEL · August 10, 2024, 12:20pm

Ok, I'll share a way for that. And I'll recommend you to use the Extension Template Repository to build extensions with ease.

TIMAI2 · August 10, 2024, 12:26pm

Or use RUSH, then most imports are automatically picked up as you add a class in your code when using IntelliJ.

Mohamed_Abdelbasset · August 10, 2024, 12:32pm

yes can i tell me how ?
intelliJ and rush

JEWEL · August 10, 2024, 12:39pm

Watch this video to learn how to install Rush.

TIMAI2 · August 10, 2024, 12:44pm

Or just follow the guide in the link I posted (if using Linux etc.)

Mohamed_Abdelbasset · August 10, 2024, 1:11pm

yes but Extension Template Repository not working with me (ant) i have this error :

Just place extension related java files only inside the src folder.

Mohamed_Abdelbasset · August 10, 2024, 3:15pm

yes that's what i do always

    <classpathentry kind="lib" path="${PROJECT_DIR}/lib/appinventor/webrtc.jar"/>
</classpath>

Copy the xml and create a .classpath file into your project root directory and paste the copied xml inside the file. If you want to add new dependencies so just make a new line at the end and set the path of the new jar.

For example:

<classpathentry kind="lib" path="${PROJECT_DIR}/lib/deps/jar-name.jar"/>

So the IntelliJ IDEA will suggest auto completion.

Hope it helps?

Mohamed_Abdelbasset · August 10, 2024, 5:35pm

thank you @ JEWEL

can you explain to me more detailed..
i said i use IntelliJ not eclipse

JEWEL · August 10, 2024, 5:45pm

This xml should work on IntelliJ IDEA. Please try.
I'm also using it for developing extensions with the Extension Template Repository.

Mohamed_Abdelbasset · August 10, 2024, 6:51pm

please please help me...... i can't do this ... ho i do it ..
