这是我在运行有关依赖项的mvn命令时返回的内容。正如我之前解释的主要问题是，当我尝试在IDE外部运行jar文件时，imageIO库无法正常工作。我想指出，所有其他功能均正常运行。您是否有解决此问题的想法？我也尝试按照此链接中的步骤操作：http://docs.geotools.org/latest/userguide/build/install/jdk.html，但我又遇到了相同的错误。

以下是我得到的新错误。似乎再次缺少与JAI库有关的内容。请看看：

答案 0 :(得分：0)
您可能还没有构建胖罐。
如果仅构建jar，则不包括依赖项，因此在IDE外部运行jar通常会导致类丢失。
您可以使用maven程序集插件或maven阴影插件来生成胖子。

您需要使用以下方法将ImageIO添加到manifestEntries：
<transformers>
<!-- This bit sets the main class for the executable jar as you otherwise -->
<!-- would with the assembly plugin -->
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">

<Specification-Title> Java Advanced Imaging Image I/O Tools</Specification-Title>

<Specification-Vendor> Sun Microsystems, Inc. </Specification-Vendor>
<Implementation-Title> com.sun.media.imageio</Implementation-Title>

</manifestEntries>
</transformer>
<!-- This bit merges the various GeoTools META-INF/services files -->
