代号一构建失败

【中文标题】代号一构建失败

【英文标题】：Codename one builds failing

【发布时间】：2012-07-07 14:29:20

【问题描述】：

我正在尝试将我的 lwit 应用程序移植到 codenameone。

我在应用程序中使用了一个 json 包。 （org.json.me）。这个包实际上是 json jar 的一部分，包含了操作 json 文件的类。

当我使用 LWUIT 构建 J2ME 时，该应用程序运行良好。

在代号为 one 的模拟器中，应用程序也可以正常运行。

当我尝试通过右键单击项目并选择“发送 J2ME 构建”来向服务器发送 J2ME 构建时，我的应用程序的构建过程崩溃并出现一些警告。

现在，我觉得服务器没有找到我的 json 包。但我需要这个构建成功。我在我的应用程序中经常使用这个 jar 的类。现在我不想迁移到内置的 json 解析器，因为我必须更改很多我希望严格避免的代码。

1)我能做些什么来解决这个问题？

2)我们不能在代号一中使用第三方 jars 吗？

【参考方案1】：

您不能在 Codename One 中更改库类路径。一切都必须是源目录的一部分才能正常工作。

Codename One 有自己的 JSON 解析器，请在 Codename One 开发人员指南中阅读。
