java - Android ant 编译失败 : java. lang.NoClassDefFou

因此，我使用 android 实用程序从头开始创建了 build.xml:

$ /opt/android-sdk-linux_86/tools/android create project --target android-6 --name Dash --path . --activity Main --package com.gtosoft.dash

然后我尝试开始编译，但它失败了!

$ ant release

我不知道为什么它在提示 com.android.jarutils.SignedJarBuilder
编辑:重新安装 SDK 后，我遇到了同样的问题 :(

$ ant -v 发布:

最佳答案

听起来(可能)是一个损坏的 SDK。你试过重新下载吗？

另一种选择是运行 ant -v而不是 ant .这将产生大量的诊断输出，并且很可能帮助您弄清楚发生了什么。
