最近新项目要需要更新发布版本号，用于标识发布的版本，网上找了下插件：buildnumber-maven-plugin 1.4 。

记录下自己使用成功过程中遇到的各种问题，以供需要的朋友参考：

插件官方网站：http://www.mojohaus.org/buildnumber-maven-plugin/usage.html(官网内附详细说明)

一、在项目pom.xml中添加相关配置

1)....中添加buildnumber-maven-plugin插件。

org.codehaus.mojo

buildnumber-maven-plugin

1.4

{0,date,yyyy-MM-dd HH:mm:ss}

timestamp

validate

create-timestamp

2)....中添加上面item：timestamp指定输出的配置文件的路径：

我把timestamp输出的版本号(时间戳格式的)放在 monitor.properties里。

...里的内容为配置文件的目录路径：src/main/resources

src/main/resources

true

3).timestamp输出属性定义：

与.properties文件中的相对应。

${timestamp}

二、jave代码中读取

monitor.properties文件中的project.build.timestamp属性，将时间戳格式转化成想要的日期格式，保存到库表。

遇到的问题：

1. 开始用的是create，但是编译会报错，替换成create-timestamp即可。

2. eclipse里excution报错：

3. maven clean install 编译工程报错：

ia-logging-api/1.1/doxia-logging-api-1.1.jar 解决：

执行buildnumber-maven-plugin插件时找不到commons-lang的StringUtils类。通过查看 maven本地仓库buildnumber-maven-plugin-1.4.pom文件，发现没有配置commons-lang包的依赖，添加配置如下依赖：

commons-lang

commons-lang

2.3

重新执行 clean install 通过！
