问题描述
我正在使用maven shade插件为我的项目生成一个合并jar。 jar是按预期生成的，当我尝试使用jar并运行它时，我得到一个
I am using the maven shade plugin to generate a consolidate jar for my project. The jar is generated as expected and when i try to use the jar and run it, i get a
我用Google搜索了上述错误消息，很多人建议排除来自META-INF目录的清单签名。因此，我已经包括从目录中排除这些文件的步骤[我看到两个文件的名称 JARSIGN_.RSA 和 JARSIGN_.SF ]，但由于某些奇怪的原因，maven shade插件无法从META-INF目录中排除这些文件。谁能解释一下我可能做错了什么？我的pom.xml在下面，我用来生成jar的命令是：
I googled the above error message and many people have suggested to exclude the manifest signatures from the META-INF directory. Thus i have included the step to exclude these files from the directory [i see two files by the name JARSIGN_.RSA and JARSIGN_.SF], but for some strange reason, maven shade plugin is unable to exclude these files from the META-INF directory. Could anyone explain me what i might be doing wrong? My pom.xml is below and the command that i am using to generate the jar is:
mvn clean package shade:shade

推荐答案
可能插件的配置语法已经改变，但是这对我来说在过去使用着色器插件版本1.5：
Maybe the configuration syntax for the plugin has changed, but this worked for me in the past with version 1.5 of the shader plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.5</version>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.DontIncludeResourceTransformer">
<resource>META-INF/JARSIGN_.SF</resource>
</transformer>
</transformers>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
我没有尝试使用通配符。但是看一下以下内容应排除所有 .SF 文件：
I have not tried to use wildcards. But looking at the documentation the following should exclude all .SF files:
<resource>.SF</resource>
