Maven package error

问题

I am working on a project which requires a geotools dependency. Before I was getting the following error:

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?

which was solved by the following dependency:

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

And the project build successfully without any error. Now, I am trying to package my project into a jar using this command:

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

But I am getting the same error message again. I don't know why it is running in intellij as a project, but not after running the package command.

Any help or hint would be appreciated.

回答1:

First, you need one of the EPSG factories (rather than xerces) to fix your first issue - see the GeoTools FAQ for more detail.

Secondly, when assembling a fat (or uber) jar you need to pay special attention to the spi control files as described in the GeoTools FAQ.

回答2:

You can check your geotools' version in maven repository. And you should ensure all geotools' version is suitable especially gt-epsg-hsql.
