NoClassDefFoundError 在 JavaFX 应用程序 运行 Proguard 之后
NoClassDefFoundError after running Proguard on JavaFX application
我在 JavaFX 应用程序上 运行ning proguard 后收到以下错误。如果不使用混淆器，应用程序 运行 没问题。我搜索了 Whosebug 并找到了一些帖子，但我尝试了一些不同的答案却没有成功。

变通
如果我将以下内容添加到 proguard 配置中，我可以解决这个问题并将其解决运行。
-dontoptimize
我想我真的很想优化，但它似乎并没有在适当的地方做太多混淆。我怎样才能解决这个问题，但尽我所能？
好吧，如果有人偶然发现了这个问题并且遇到了类似的问题，我已经通过不将我的 jar 文件移动到 运行 之前的另一个位置来解决我的问题。我收到 NoClassDefFoundError 错误，因为尝试使用的 类 位于 libs 文件夹中，在我移动 .jar（而不是 libs 文件夹）后无法访问该文件夹。一个非常容易解决的问题，但是在 Whosebug 上找到了这么多不同的建议，我没有想到现在看起来非常明显的是什么。
我在 JavaFX 应用程序上 运行ning proguard 后收到以下错误。如果不使用混淆器，应用程序 运行 没问题。我搜索了 Whosebug 并找到了一些帖子，但我尝试了一些不同的答案却没有成功。

变通 如果我将以下内容添加到 proguard 配置中，我可以解决这个问题并将其解决运行。
-dontoptimize
我想我真的很想优化，但它似乎并没有在适当的地方做太多混淆。我怎样才能解决这个问题，但尽我所能？
好吧，如果有人偶然发现了这个问题并且遇到了类似的问题，我已经通过不将我的 jar 文件移动到 运行 之前的另一个位置来解决我的问题。我收到 NoClassDefFoundError 错误，因为尝试使用的 类 位于 libs 文件夹中，在我移动 .jar（而不是 libs 文件夹）后无法访问该文件夹。一个非常容易解决的问题，但是在 Whosebug 上找到了这么多不同的建议，我没有想到现在看起来非常明显的是什么。
