Maven包错误

Question

我正在做一个需要 geotools 依赖项的项目。在我收到以下错误之前：

Exception in thread "main" java.lang.IllegalStateException: cannot initilize transformation: Authority "EPSG" is unknown or doesn't match the supplied hints. Maybe it is defined in an unreachable JAR file?

已通过以下依赖解决：

 <dependency>
      <groupId>xerces</groupId>
      <artifactId>xercesImpl</artifactId>
      <version>2.11.0</version>
 </dependency>

并且项目构建成功，没有任何错误。现在，我正在尝试使用此命令将我的项目打包到一个 jar 中：

mvn assembly:assembly -DdescriptorId=jar-with-dependencies

但我又收到同样的错误信息。我不知道为什么它在 intellij 中是运行作为项目，但在运行包命令之后不是

如有任何帮助或提示，我们将不胜感激。

Answer 1

首先，您需要一个 EPSG 工厂（而不是 xerces）来解决您的第一个问题 - 请参阅 GeoTools FAQ 了解更多详细信息。

其次，在组装 fat（或 uber）jar 时，您需要特别注意 GeoTools FAQ 中描述的 spi 控制文件。

Answer 2

您可以在 Maven 存储库中检查您的 geotools 版本。并且您应该确保所有 geotools 的版本都适用，尤其是 gt-epsg-hsql。
