Android Room and Data Binding compile-time errors
I’m building things with a combination of the new Room ORM and Data Binding, and I find that when Room has compile errors they express as hundreds of lines of Error:(6, 31) error: cannot find symbol class BR
and related things, and no actual real error.
Turns out, javac will print a maximum of 100 compilation errors, and when dealing with preprocessors you often want the last error message, not the first. Put this in your top-level build.gradle
file and become happy:
allprojects {
gradle.projectsEvaluated {
tasks.withType(JavaCompile) {
options.compilerArgs << "-Xmaxerrs" << "4000"
options.compilerArgs << "-Xmaxwarns" << "4000"
}
}
}
