Error occurs during the build of distributable jar #30

Closed ghost closed 13 years ago

ghost commented 13 years ago

What steps will reproduce the problem?

  1. sbt proguard

Following error occurs:

proguard: java.io.IOException: Can't read [/home/andrew/jdk1.7/jre/lib/rt.jar] Can't process class [com/oracle/net/Sdp$1.class](Unsupported version number [51.0] for class format))

What version of the product are you using? On what operating system?

java version "1.7.0" Java(TM) SE Runtime Environment (build 1.7.0-b147) Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

I googled that its because build process invoke proguad 4.6, which dont suppot jdk7, instead of new proguard-4.7

In that case, it's more a bug again the sbt proguard plugin, is it not?

This has been addressed upstream in the SNAPSHOT repo.

https://github.com/siasia/xsbt-proguard-plugin/issues/8

For now, I changed the plugins.sbt to depend on xsbt-proguard-plugin-0.1-SNAPSHOT so things will build for java 7 users. Pushed in 693f8c4ebfc.
