codenameone - 由于 retrolambda 问题，构建 CN1 应用程序不起作用

问题描述

我的应用程序将不再为 iPhone 和 Android 构建，显然是由于 retrolambda 的问题。

我已经有一段时间没有构建了（我认为是 6-7 个月），但我认为我的应用程序使用 lambda 函数的方式没有显着变化（但我可能错了，因为我不确定如何阅读错误消息），所以我想知道 CN1 构建过程中是否发生了某些变化？

如果没有，任何有关如何“解码”以下错误日志以了解问题的帮助都会非常棒。我想我已经确定了有问题的代码，但它的编写方式似乎与之前成功编译的方式相同。

解决方案

这在复古 lambda 阶段失败，但与此无关。看到这个错误：

ParseObject您的构建中缺少。如果项目中存在 build、bin、target 和 dist 目录，请尝试删除它们。似乎存在未正确包含的依赖项。还要确保您没有以任何方式更改类路径。
