java - OpenSuse 13.2 上的 Qt for Android

Question

我刚刚从 Opensuse 13.1 升级到 13.2，无法再让我的 Android Qt 开发正常工作。我的调查使我相信它更像是一个 android 开发问题 (ant)，而不是与 Qt 有关的任何问题。

我在尝试部署示例项目时遇到以下错误。我发现它可能与缺少的 xml-apis 包有关，可能 xml-commons 包应该提供此功能，但它们似乎没有。

我对 Java 一点都不熟悉，并且已经坚持了一段时间。任何建议表示赞赏。

Answer 1

我通过使用 opensuse 13.2 软件管理器删除 'xml-commons'、'xml-commons-jaxp-1.3-apis' 并安装 'xerces-j2'、'xerces-j2-xml-apis' 解决了同样的问题， 'xerces-j2-xml-resolver' 和我的项目报告构建成功。
完成澄清步骤:

1. 从“Yast2”控制中心打开“软件管理”。
2. 搜索“xml-commons”。
3. 如果是，请取消选中“xml-commons”、“xml-commons-jaxp-1.X-apis”已检查(已安装)[注意:X 代表任何版本号]，以及接受以完全卸载该软件。
4. 现在搜索“xerces-j2”。
5. 检查(安装)“xerces-j2”、“xerces-j2-xml-apis”、结果列表中的“xerces-j2-xml-resolver”并接受安装他们或者如果他们目前正在检查中，请不要碰他们!
   
   这就是我对这个问题的全部解决方案。
