maven scala java

• 项目中,Java和scala混用,java调scala,scala调java.用 mvn package的时候报错.
• 总结出了以下简单的 xml.使之不抱错

com.typesafe.config.ConfigException$Missing: No configuration setting found for key ‘akka.remote.artery’

• 想用一个最简的 plugin错误百出.
• 决 解

//这就maven-shade-plugin 的配置,如果打一个大包.引入的jar包中都有  **.**文件,正常情况下.只会随机留下一个,而用
transformer 可以配置把所全文件名相同的配置合成一个.
-------
						<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
							<resource>reference.conf</resource>
						</transformer>
------------
这个为解决上面问题的办法.

					<transformers>
						<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
						<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
							<resource>reference.conf</resource>
						</transformer>
						<transformer implementation="org.apache.maven.plugins.shade.resource.DontIncludeResourceTransformer">
							<resource>log4j.properties</resource>
						</transformer>
						<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
							<resource>META-INF/spring.handlers</resource>
						</transformer>
						<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
