@lihuazhang 求帮助。
#1 楼 @benlooking beta1 有问题很正常吧。。。 等正式版呗，没必要在这种 beta 版本上花时间。 而且这个日志我也分析不出来。。
#1 楼 @benlooking 你是更新到了 beta1 ，然后启动 server 就出错了？ 没跑测试用例？
#3 楼 @lihuazhang 启动 server 没有出错，刚开始跑用例就出错了。但是同样的例子在 0.18 版本是 ok 的。。
试试删除机器上之前安装的 bootstrap.jar, 貌似是 jar 的版本不对
#5 楼 如@seveniruby所说，确实是 jar 版本的问题。
解决办法：删掉 AppiumBootstrap.jar
255|root@android:/data/local/tmp # ls
ls
AppiumBootstrap.jar
box
dalvik-cache
dd0d5eee21f038ba307089120db2bce9.apk
strings.json
uidump.xml
root@android:/data/local/tmp # rm AppiumBootstrap.jar
rm AppiumBootstrap.jar
root@android:/data/local/tmp # ls

box
dalvik-cache

uidump.xml
#6 楼 @benlooking 恩, 错误信息 log 里面也暗示了, 我也是猜测的
怎么删掉机器上之前安装的 bootstrap.jar
@benlooking，@seveniruby,我也遇到这个问题，但删除 AppiumBootstrap.jar 后跑测试用例又报错了：

请教下怎么解决？谢谢
#9 楼 @cywin 这个问题解决了吗？

#10 楼 @huangrui127 惭愧，没解决。后来不知道换了一台手机跑又没错了。
