I'm trying to use Natty NLP library in my Android project.
I've set up new hello world project in IntelliJ with Maven (as described in this article; just downloaded the template) and added Natty as a dependency.
public void onCreate(Bundle savedInstanceState)
{
Parser parser = new Parser();
List<DateGroup> groups = parser.parse("two days after christmas at 19");
for (DateGroup group: groups) {
List<Date> dates = group.getDates();
for (Date date: dates) {
Log.e("DATE", date.toString());
}
}
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
Everything seems to work just fine, it parses dates in decent time... but compilation takes almost 5 minutes! It would be OK if it was one time scenario to compile dependencies. But it takes 5 minutes every time I change anything in my Activity class. Which is unacceptable.
IntelliJ says it spends most time "Executing DEX". Compilation outputs a lot of warning messages:
Information:Compilation completed successfully with 41 warnings in 4 min 47 sec
Information:0 errors
Information:41 warnings
Warning:Android Dex: [helloworld] warning: Ignoring InnerClasses attribute for an anonymous inner class

Warning:Android Dex: [helloworld] compiler that did not target the modern .class file format. The recommended
Warning:Android Dex: [helloworld] solution is to recompile the class from source, using an up-to-date compiler

Warning:Android Dex: [helloworld] this warning is that reflective operations on this class will incorrectly

Is there any way to speed things up? Maybe android:dex doesn't have to be invoked every time? Or maybe there is a way to compile dependencies "correct way"?
