Hi @JEWEL
How can I build extension builder app like EIDE with Fast? Is this a difficult job?

I am uncertain, but this task may prove to be quite challenging.

Am having 12 errors from missing depes package names, but code itself seems okay

After reading, I found that am supposed to extract the .jar file class from .aar? The I did that yet still missing package names

Can you please explain how it works with depes

96

Your project structure is wrong. You should put AARs in $PROJECT_DIR/deps directory, not in the $PROJECT_DIR/libs. Also, you’re defining AARs in a wrong way in fast.yml. The correct way is below:

dependencies:
- exoplayer-2.19.1.aar

Run fast sync once before building the project or editing sources.

And if you are interested in accessing premium features, please let me know.

You gotta define dependencies in fast.yml.

Check out the open source project below to learn more:

I just deleted this line, now it works.

What an amazing tool :fire::fire::fire:

Since its my first time of using Deps, i still learning many thing on how to control it.

After the compilation, the size of the extension is too big :smiley: 7+MB

Is there any way of reducing the size when compiling?

103

To optimize the extension size, you may execute the ProGuard/R8 task.

ProGuard:

fast build -r

R8:

fast build -s

It works when I visit the URLhttps://repo1.maven.org/maven2/net/openid/appauth/0.11.1/appauth-0.11.1.aar , but it does not work with Gradle. :exclamation_question_mark:

  1. Does Fast support the latest version of JDK?
105

Try with v5.6.0. A clean (full) installation is required. (v5.6.0 is comes with a Gradle version update)

However, as a quick solution you may use the Maven resolver. To enable maven resolver make below changes in fast.yml:

resolver: maven

Yes, FAST-CLI is compatible from JDK8 to JDK25+.

If you are using JDK 8 or 11, kindly consider installing a more recent version of either JDK 8 or 11. Older builds of the JDK may cause this particular issue.

Working fine with openjdk version "1.8.0_422-422"
