Apache Tika 编译错误

Question

我试图遵循看起来非常简单的compilation instructions for Apache TikaJAXRS。我运行正在使用 Windows 8.1 64 位。

从 Apache Tika 下载页面下载最新的稳定源代码或从 Github、
使用 Maven 构建源代码，
运行 Apache Tika JAXRS 服务器。

好的。我已经完成了第 1 步，但在第 2 步时遇到困难。显然这里有一些未写明的先决条件，因此我尝试按如下方式解决它们：

已安装Java SDK 8u25
将 JAVA_HOME 变量设置为 C:\Program Files\Java\jdk1.8.0_25
将 CLASSPATH 变量设置为 .
已将 JDK BIN 目录添加到 PATH 变量：C:\Program Files\Java\jdk1.8.0_25\bin
已将 Maven BIN 目录添加到 PATH 变量：C:\apache-maven-3.2.5\bin

然后从 tika-1.7 目录（用于 src 下载的 zip 内容）我运行 mvn install。编译愉快地进行了几分钟，然后吐出下面粘贴的错误输出，此时编译似乎冻结了。

问题看起来可能是这个 - https://issues.apache.org/jira/browse/TIKA-1276 那里有一些关于重新创建捆绑包和修改其中的文件以解决问题的讨论，但坦率地说，我发现奇怪的是我必须跳过这样的箍才能获得 Tika 的工作副本 - 没有二进制分发提供！

我需要做什么才能解决这个编译问题？

Answer 1

正在提升对答案的评论...

我不确定为什么您的构建在该测试中失败，因为它通过了我和自动 build/test 系统。但是...您可能不想做任何事情！

如果你去 Apache Tika download page，你会看到 link 下载最新稳定的 Tika Server 运行nable jar。按照那个 link，选择你最喜欢的镜像，下载，验证校验和运行。简单！

如果您确实需要从源代码构建 Tika 服务器（例如，如果您要对其进行更改），您可以通过运行ning [=10= 跳过单元测试] 这将在没有测试的情况下进行构建，或者您可以在源代码检出的根目录中编辑 pom.xml 并注释掉行 <module>tika-bundle</module> 以从构建中排除整个包部分（测试和所有） .如果您只想使用 Tika 服务器，那么您不需要 OSGi 包，因此可以安全地跳过它

Answer 2

当您尝试使用 JDK 8 构建 tika 时会发生此错误。有一个 pull request 可以解决此问题。
