Currently, it’s not possible. We’d like the same feature for C++ as well, in order to build extensions with more commonly used functionality (e.g OpenSSL etc)

I didn’t find a ticket for it though, so I created one: DEF-3348
I don’t think it will be done until a few months from now though.

So,is it isolated between extensions?Extension can only be used by lua or script or gui_script?

Extension can be used by script and gui_script and module.

If you have A.java and B.java you could merge them into the same extension as well.

I put A.java and B.java into one extension, and A.java with first line package a.b.c.d, B.java with first line package e.f.g.h;
when I import a.b.c.d; in B.java, It builds failed.How can I fix this?

It should be possible, we just did such a test:

A.java

package a.b.c.d;

public class A {
    public static void LOL()
    {
        System.out.println("LOL");
    }
}

B.java

package e.f.g.h;

import a.b.c.d.A;

public class B {
    public static void LOL2() {
        A.LOL();
    }
}

Here is the full extension we used:

Does the java file must be in the src folder?I found if I place A.java outside src folder, It won’t be bundled in classes.dex

Yes, the source files need to be placed in the src folder: https://www.defold.com/manuals/extensions/
