最近新項(xiàng)目要需要更新發(fā)布版本號(hào)，用于標(biāo)識(shí)發(fā)布的版本，網(wǎng)上找了下插件：buildnumber-maven-plugin 1.4?。

記錄下自己使用成功過程中遇到的各種問題，以供需要的朋友參考：

插件官方網(wǎng)站：http://www.mojohaus.org/buildnumber-maven-plugin/usage.html(官網(wǎng)內(nèi)附詳細(xì)說明)

一、在項(xiàng)目pom.xml中添加相關(guān)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指定輸出的配置文件的路徑：

我把timestamp輸出的版本號(hào)(時(shí)間戳格式的)放在 monitor.properties里。

...里的內(nèi)容為配置文件的目錄路徑：src/main/resources

src/main/resources

true

3).timestamp輸出屬性定義：

與.properties文件中的相對(duì)應(yīng)。

${timestamp}

二、jave代碼中讀取

monitor.properties文件中的project.build.timestamp屬性，將時(shí)間戳格式轉(zhuǎn)化成想要的日期格式，保存到庫表。

遇到的問題：

1. 開始用的是create，但是編譯會(huì)報(bào)錯(cuò)，替換成create-timestamp即可。

2. eclipse里excution報(bào)錯(cuò)：

解決辦法：

參考http://blog.csdn.net/huweijun_2012/article/details/51073782

3. maven clean install 編譯工程報(bào)錯(cuò)：

執(zhí)行buildnumber-maven-plugin插件時(shí)找不到commons-lang的StringUtils類。通過查看?maven本地倉庫buildnumber-maven-plugin-1.4.pom文件，發(fā)現(xiàn)沒有配置commons-lang包的依賴，添加配置如下依賴：

commons-lang

commons-lang

2.3

重新執(zhí)行 clean install 通過！
