java - "Failed to export application" in Eclipse 4.4.1 for Android with ADT 23.0.4 -

when want export android app eclipse, export process starts after few seconds (when whole process should take minute) fails. following error message appears:

failed export application

that's eclipse telling me. i'm using ecliipse 4.4.1 android development toolkit 23.0.4.1468518.

when right-click app, choose "android tools" , "export unsigned application package", fails again, more verbose error messages:

as can see, says:

'android release export' has encountered problem.

failed export application

and strangely, lists file bin/$1$1.class apparently cannot found. there's no obvious reason why file shouldn't found, however.

only when delete folders bin , gen , clear project, works. once -- , after every successful run on device or export apk, have repeat step described before.

any ideas why happens? lot in advance!

i had multiple issues export application package in eclipse before. switching project - build automatically off helped, deleting bin folder , cleaning project helped. best , working solution found migration ant build.

if interested, here how works. surprisingly simple. navigate project's folder , execute

android update project -p . 

it created build.xml file. repeat same used library projects, if any. , done. calling ant release create released apk-file. if want app signed, add key.store, key.alias, key.store.password , key.alias.password local.properties file inside project. can build new apk single command. hope can you.
