在 debian 上编译最新版本的 Apache Tika 时出现此错误。任何帮助将不胜感激。

我已经从 tika.apache.org/download.html 下载了最新版本。安装了具有 aptitude 的 maven。我使用debian。并且还安装了 sun-java6-jdk。设置 JAVA_HOME 变量。然后我就去 base tika 文件夹并运行“mvn clean install”。更有趣的是，几天前我可以将它安装在另一台 debian 服务器上而没有任何问题。

Based on your stack trace, I don't think you're using the Sun JDK. Instead, I think you're using GCJ (the GNU Java stuff) - if you look in the stacktrace you'll see references to libgcj.so which is the giveaway.

I think therefore that what you need to do is use update-alternatives to pick the Sunk JDK / JRE instead of the GNU GCJ one. After that, Tika ought to compile fine.

Try:

update-alternatives --list java
update-alternatives --list javac
update-alternatives --display java
update-alternatives --display javac

The to pick you can use

update-alternatives --config java
update-alternatives --config javac

(You might also want to update jar, jarsigner and a few others too)
