So I have an android project setup and I am using Kotlin as primary language. I have also used Databinding Library from Jetpack. Out of curiosity, I tried to build the app from CLI. The application is building and running fine from the GUI, Run button. As far as I know I can build and run from the CLI too, right? So I ran
./gradlew assembleDebug
and I was not able to build the application. I got the following output on my terminal:
> Task :app:kaptDebugKotlin FAILED

Now I am guessing, this error has something to do with Databinding but I could be wrong. I also tried to look at some open source android projects using CI/CD in their projects to see what they are doing but I could not find one which uses DataBinding library. All they had was the same two three gradle scripts which are not running for me. Do suggest me a solution to this so that I will be able to build and run my application from the command line.
So what turns out is JAXB (Java Architecture for XML Binding) seems missing in Java 11 which was being used in my system. When I did java -version on my terminal, I got Open JDK 11 which was located in usr/lib/jvm/. So I went ahead and removed it.
sudo rm -r /usr/lib/jvm/java-11-openjdk-amd64
Then I installed Java 8 Open JDK
sudo apt install openjdk-8-jdk openjdk-8-jre
Now I have java 8 which is also used by Android Studio and has the JAXB api. Do correct me if I am wrong as this is a self baked solution and I am not sure about a lot of things here.
But yeah ./gradlew assembleDebug and other commands works fine now.
