关于d2rq在执行dump-rdf报错Version number may be negative or greater than 255

在 https://github.com/unicode-org/icu/releases/tag/release-68-2 中下载。通过generate-mapping命令生成了.ttl文件后，执行dump-rdf命令将ttl文件生成.nt文件报错。删除，然后将下载的 icu4j-68_2.jar 复制进去。

解决办法

在 https://github.com/unicode-org/icu/releases/tag/release-68-2 中下载icu4j-68_2.jar这个文件，将d2rq-0.8.1\lib\arq-2.9 中的 icu4j-3.4.4.jar 删除，然后将下载的 icu4j-68_2.jar 复制进去。
