Gracefully handle missing gradle definitions (use default values if definition is missing)
I usually do following in my projects:
1) define a versions.gradle file, e.g.:
ext {
setup = [
compileSdk: 28,
enableDataBinding: true,
minSdk : 16,
targetSdk : 28
]
androidx = [
supportv4: "1.0.0",
appcompat: "1.0.0",
cardview: "1.0.0",
viewpager: "1.0.0",
material: "1.0.0"
]
}
2) I add this versions file to my projects gradle file:
apply from: './versions.gradle'
3) I use the versions from the file in all my project gradle files for consistant library versions, like e.g.:
implementation "androidx.appcompat:appcompat:${androidx.appcompat}"
Question
How can I handle this gracefully in open source libraries I use? I want that if someone checks out my library and adds the library directly to his projects, that some default version is provided so that this line implementation "androidx.appcompat:appcompat:${androidx.appcompat}" won't throw any error (${androidx.appcompat} should be replaced by 1.0.0 e.g. in this case).
Is there some way to solve this easily? I want that the version file is used if available and a fallback version is used otherwise...

You can use elvis operator to replace default version if defined version not found like this :implementation "androidx.appcompat:appcompat:${androidx.appcompat ?: 1.0.0}"

Thanks, that's the perfect solution. Better than some if in my gradle file and defining all missing definitions. One thing though, the number must be put in'

Trying Elvis operator for placing default value can do that trick, so replacing it with operator like below works :
implementation "androidx.appcompat:appcompat:${androidx.appcompat ?: 'default value here'}"
More from here.
