推荐答案

根据 Apache Tika 的网站，所有tika-server.jar 的新版本将需要 Java 8.

According to Apache Tika's site, all new versions of the tika-server.jar will require Java 8.

2018 年 4 月 24 日:Apache Tika 发布Apache Tika 1.18 已经发布！此版本包括错误修复(例如从 PPT 中的分组形状中提取)、安全修复和依赖项升级.请注意:下一个版本将需要 Java 8.请参阅 CHANGES.txt 文件以获取发行版中的完整更改列表，并查看下载页面以获取有关如何获取 Apache Tika 1.18 的更多信息.

24 April 2018: Apache Tika Release Apache Tika 1.18 has been released! This release includes bug fixes (e.g. extraction from grouped shapes in PPT), security fixes and upgrades to dependencies. PLEASE NOTE: The next versions will require Java 8. Please see the CHANGES.txt file for the full list of changes in the release and have a look at the download page for more information on how to obtain Apache Tika 1.18.

tika Python 库的当前过时文档声称需要 Java 7，但现在必须安装 Java 8.这是因为如果在您的临时文件中找不到当前版本的 tika-server.jar，则会在运行时自动下载.

Current outdated docs for tika Python library claim that Java 7 is needed, but now Java 8 must be installed. This is because the current version of tika-server.jar is automatically downloaded at runtime if not found in your temp file.

安装 Java 8 后，我的基本测试代码启动了服务器并正常运行.

After installing Java 8, my basic test code launched the server and worked without error.
