我有同样的错误。我再次检查sdk更新，安装它们并在eclipse中，我检查了更新（help-＆gt;检查更新）。 重新开放日食后，我现在恢复正常。希望这有帮助

您一定有正确的dependencies吗？您安装了哪个eclipse版本？哪个JRE / JDK用于运行eclipse？
Bad version number表示预期的目标java版本与您使用的版本之间存在不匹配（请参阅here）。
答案 2 :(得分：0)
在我的情况下，计算机重启解决了所有问题，而无需重新安装ADT插件。 顺便说一下，我正在使用MAC + ADT_v22
答案 3 :(得分：0)
我的某个项目中有一些错误。我只是
switch工作区，问题就解决了。
打开 Eclipse 。转到文件菜单 - ＆gt;切换工作区 - ＆gt;其他并创建一个新的工作区路径。你很高兴。
