  1. 通过dependency:tree是命令来检查版本冲突

mvn -Dverbose dependency:tree

2.install 成功 build 报包找不到
　　mvn终端 mvn idea:idea (下载未下载完成的包)
　　invalidate caches 重新启动idea

3.获取构建时间：
　　a.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.4</version>
    <executions>
        <execution>
            <phase>validate</phase>
            <goals>
                <goal>create-timestamp</goal>
            </goals>
            <configuration>
                <timestampFormat>yyyy-MM-dd HH:mm:ss</timestampFormat>
            </configuration>
        </execution>
    </executions>
</plugin>
　　b.

<properties>
    <project.build.timestamp>@timestamp@</project.build.timestamp>
</properties>
　　c. properties文件配置
　　project.build.timestamp =@project.build.timestamp@

4.jar 打包 依赖包分离
