在http://doc.akka.io/docs/akka/snapshot/general/configuration.html上有关于从“胖罐”运行Akka的警告。问题是存在多个
reference.conf配置文件，并且Maven程序集或shade插件的默认行为是用较新的实例覆盖较早的配置文件实例。
要解决此问题，建议的方法是使用Maven
shade插件生成可执行jar，并将其配置为将所有
resource.conf文件附加到单个文件中，而不是覆盖。建议的Maven阴影插件配置如下所示：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>1.5</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <shadedArtifactAttached>true</shadedArtifactAttached> <shadedClassifierName>allinone</shadedClassifierName> <artifactSet> <includes> <include>*:*</include> </includes> </artifactSet> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>reference.conf</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <manifestEntries> <Main-Class>akka.Main</Main-Class> </manifestEntries> </transformer> </transformers> </configuration> </execution> </executions></plugin>
