java - Maven包错误

问题描述

我正在开发一个需要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?

这是通过以下依赖解决的：

 <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，我正在尝试使用以下命令将我的项目打包到一个 jar 中：

mvn 程序集：程序集-DdescriptorId=jar-with-dependencies

但是我再次收到相同的错误消息。我不知道为什么它作为一个项目在intellij中运行，但在运行 package 命令之后却没有。

任何帮助或提示将不胜感激。

解决方案

首先，您需要一个 EPSG 工厂（而不是 xerces）来解决您的第一个问题 -有关更多详细信息，请参阅GeoTools 常见问题解答。

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。
