Eclipse的信息：

eclipse.buildId=M20120208-0800 
java.version=1.5.0_30 
java.vendor=Apple Inc. 
BootLoader constants: OS=macosx, ARCH=x86, WS=cocoa, NL=fr_FR 
Framework arguments: -keyring /Users/stef/.eclipse_keyring -showlocation 
Command-line arguments: -os macosx -ws cocoa -arch x86 -keyring /Users/stef/.eclipse_keyring -showlocation 

Java版本：

java -version 
    java version "1.5.0_30" 
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_30-b03-389-9M3425) 
    Java HotSpot(TM) Client VM (build 1.5.0_30-161, mixed mode, sharing) 

在Eclipse，它是目前設置爲Java編譯器1.5和J2SE JRE 5.0。我也試着用Java Compiler編譯爲1.6和JRE Java SE 6，結果仍然相同。

我在做什麼錯？

Answer 1

這是最有可能與現在ADT 17 requiring Java 1.6：

的Java 1.6或更高版本的ADT 17.0.0。

因此，您需要將Java版本從1.5.0_30更新到更新的版本。

Answer 2

很顯然，錯誤在於.class文件，它不是java的一部分，而是（我相信）錯誤所在的apk（就像隱藏的豹一樣，當你打開首選項時等待打擊）。你有沒有嘗試重新安裝apk？這可能是因爲你的下載足以導致問題。這種情況在.iso文件中會發生很多，但即使是像apk下載一樣小的東西也可能會搞砸。嘗試從系統中徹底清除並重新安裝它（與工具一起，錯誤也可能在那裏）。如果這不是你的問題，你可以去跟蹤這個所謂的.class文件（使用瀏覽器搜索）並找到版本號說什麼。任何這些都是一種選擇。

希望這有助於

Answer 3

我也有這個問題。我只是通過下載最新版本的Eclipse來解決它，並從頭開始重新安裝Android工具和SDK。

請注意，我只使用64位Eclipse成功。 32位版本不適合我。

我正在運行Mac OS X 10.5 Leopard。當問題發生時，我的Java 1.6運行，所以我不必更新JRE或JDK來解決問題。

該解決方案由薩蒂揚Kandula在下面的鏈接給出： https://bugs.eclipse.org/bugs/show_bug.cgi?id=376434

Answer 4

更新了我的JDK我的Mac（運行Leopard），刪除的Eclipse SDK &。重新安裝Eclipse（64位版本）& SDK，並獲得成功。

Answer 5

與OP類似，如果不是同樣的問題。嘗試了一些不同的東西（例如）：舊的SDK，舊的ADT插件。我正在使用OS X（10.5）。最終，我安裝了64位的Eclipse（eclipse-SDK-3.7.2-macosx-cocoa-x86_64.tar.gz），它看起來沒問題。

將更新，如果有問題。
