【问题描述】：

我刚刚从 Opensuse 13.1 升级到 13.2，无法再让我的 Qt 开发为 android 正常工作。我的调查让我相信，这更像是一个 android 开发问题 (ant)，而不是与 Qt 有任何关系。

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 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 一点也不熟悉，并且已经坚持了一段时间。任何建议表示赞赏。

【问题讨论】：

我看了推荐使用Oracle JDK进行android开发。你可以试试。 fr.opensuse.org/SDB:Installer_Java#Installer_Java_d.27Oracle

谢谢，但我在使用 Oracle JDK 时仍然遇到同样的错误

【参考方案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。 澄清的完整步骤：

从“Yast2”控制中心打开“软件管理”。 搜索“xml-commons”。 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]，并且 接受完全卸载该软件。 现在搜索“xerces-j2”。 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被检查，不要碰他们！ 这就是我解决这个问题的全部方法。

这也解决了我的问题。真的非常感谢。
