gradle build Javadoc task fails with 'unknown tag: attr'

Question

I am attempting to build the android-autofittextview project from the command line using gradle. However, it fails every time with the following error:

/Users/me         


        

Answer 1

A javadoc tool has an argument to specify custom tags. That parameter is -tag.

To pass that argument from gradle build file to javadoc tool add a configuration to your build.gradle as follows:

javadoc {
    options.tags = [ "attr" ] 
}

Custom tags can be specified as single argument with :::

javadoc {
    options.tags = [ "attr:a:head" ] 
}
