Error about sun/misc/BASE64Encoder on Eclipse

Question

when i run my app in mac, and show up this message Errors occurred during the build. Errors running builder \'Android Package Builder\' on project \'IMPEXP\'. sun/misc/BASE

Answer 1

The Android code you are using is trying to use the sun.misc.BASE64Encoder class.

This deprecated class has been removed from Java 9 so this is not going to work.

You will need to switch back to Java 8 or find an update to the Android code (if there is one).

Answer 2

In my case it was something very crazy. I have to download the eclipse IDE Version NEON

Since the project is old almost from 2014

Attached the url of the IDE for which you need it: Eclipse IDE NEON

I also had to follow the same installation steps

Answer 3

I'm working with Windows 7. I had to change the preferences and the ini file. Both had C:\Program Files\Java\jdk-12.0.1\bin which I changed to C:\Program Files\Java\jre1.8.0_221\bin. It now works!

Answer 4

As others have pointed out already, this is a compatibility issue—you need exactly Java 8 to run Eclipse.

• Install JDK 8 if you don’t have it already.
• In Eclipse, go to Window > Preferences > Installed JREs. Make sure Java 8 appears in the list and is selected. After that, close Eclipse.
• Additionally, eclipse.ini also has a reference to the Java VM it uses. Make sure the VM it points to is Java 8 (see link on how to find it and how to set VM preferences).
• Restart Eclipse and try again.
