Fail to migrate v5 to v6

Ionic Framework
1

Hi! I am following this tutorial to migrate v5 to v6. When using npx cap migrate, I received the following error:

√ Migrating build.gradle file. in 2.66ms
√ Replacing deprecated compileSdkVersion from build.gradle in 723.00μs
× Migrating variables.gradle file. - failed!
[error] Failed to migrate: TypeError: Invalid Version: ext {
        minSdkVersion = 22
        compileSdkVersion = 34
        targetSdkVersion = 34
        androidxActivityVersion = '

Has anyone encounter this issue before? Thank you.

    androidxAppCompatVersion = '1.6.1'
    androidxCoordinatorLayoutVersion = '1.2.0'
    androidxCoreVersion = '1.10.0'
    androidxFragmentVersion = '1.5.6'
    junitVersion = '4.13.2'
    androidxJunitVersion = '1.1.5'

}facing same issue this is my variables.gradle. I tried updating it to latest file shown on Updating to 6.0 | Capacitor Documentation still getting same error.

Can you put it in a code block so it can be copy/pasted as is? if introducing it as text the quotes are converted and are not valid for gradle files.

Also, can you answer the questions about the operating system and node/npm versions?

I ran into the same issue. Check the line endings of your variables.gradle file. Mine were mixed between CRLF and LF. Converting them all to just LF worked. On Windows you can use a tool like Notepad++ to accomplish this.

Good luck!
