ProGuard didnt compile with Joda Time used in Windows

问题

Actually this is an answer and not a question anymore: I did spent many hours on Windows using JodaTime to be included in my Android project using ProGuard

Proguard Configuration:

-libraryjars C:\Users\Reto\Documents\GitHub\advanceIT\LoveClockPAY\libs\joda-time-2.1.jar

I had the following errors:

1. ProGuard didnt find my JAR and said:

   Can't read [C:\Users\Reto\Documents\GitHub\advanceIT\LoveClockPAY\libs\joda-time-2.1.jar] (No such file or directory)

   Solution

   -libraryjars libs/joda-time-2.1.jar

2. ProGuard didnt wanna compile and thrown many line of errors like this:

   Warning: org.joda.time.base.AbstractDuration can't find referenced class org.joda.convert.ToString

   Solution

   # Exclude those 2 dependency classes, cause otherwise it wont compile

   -dontwarn org.joda.convert.FromString

   -dontwarn org.joda.convert.ToString

回答1:

Or alternatively as solution for problem 2. you can add an implementation included in joda-convert-xxx.jar. It can be found on the joda-convert homepage

Then just add a following line into your proguard configuration :

-libraryjars YOUR_DIR_WITHS_JARS/joda-convert-1.3.1.jar
