no build instructions -- can't build

[csells]

I'm doing my best to be able to build what looks like an Ionic app but I'm having no luck. I installed gradle 8.x (the latest stable version), but it's still failing the build looking for gradle 8:

npx cap run android --target=Pixel_6_Pro_API_31  --external --no-sync
✖ Running Gradle build - failed!
[error] 
        FAILURE: Build failed with an exception.
        
        * What went wrong:
        A problem occurred configuring root project 'android'.
        > Could not resolve all files for configuration ':classpath'.
        > Could not resolve com.android.tools.build:gradle:8.0.0.
        Required by:
        project :

        library for use during runtime, compatible with Java 8, packaged as a jar, and its dependencies declared
        externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.0.2' but:

        and its dependencies declared externally:
        - Incompatible because this component declares a component for use during compile-time, compatible with Java 11
        and the consumer needed a component for use during runtime, compatible with Java 8
        - Other compatible attribute:
        - Doesn't say anything about org.gradle.plugin.api-version (required '8.0.2')
        - Variant 'javadocElements' capability com.android.tools.build:gradle:8.0.0 declares a component for use during
        runtime, and its dependencies declared externally:

        - Other compatible attributes:
        - Doesn't say anything about its target Java version (required compatibility with Java 8)
        - Doesn't say anything about its elements (required them packaged as a jar)

Of course, I'm flying blind here, since there are no instructions that I could find that say how to build things.

P.S. I'm trying to build on a mac M1 box. thanks.
