Flashout 0.2.0.x not working in Eclipse 3.1 RC2

Flash Add comments

I just upgraded to Eclipse 3.1 (RC2) and installed Flashout but was unable to set the preferences for Flashout. The following error occurred when I clicked the Flashout option in the Preferences window:

Unable to create the selected preference page.
Reason: Plugin com.potapenko.flashout was unable to load class com.potapenko.flashout.preferences.PreferencesRoot

After checking the log files from Eclipse (workspace->.metadata->.log) I found out that the following seemed to be the root error:

java.lang.UnsupportedClassVersionError: com/potapenko/flashout/FlashoutPlugin (Unsupported major.minor version 49.0)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)

The result of a Google search pointed out that I might be using the wrong java version and indeed, that was it. Make sure you’re using Java 1.5.

To know what Java version you’re using, open a command prompt and type:

java -version

You can also try one of the other options listed on this page.
You can get the latest version here.

Have fun!
