为什么`grails war`每次都会创建一个不同的WAR？

Question

为什么grails war每次都会生成一个不同的WAR文件？在命令行中，我观察到以下行为。

$ grails test war 
| Done creating WAR target/foo-2.5.3.war 
MacBook-Air:foo mba$ md5 target/foo-2.5.3.war 
MD5 (target/foo-2.5.3.war) = af45e22b24d158a72c9a0db67cd31417 

$ grails test war 
| Done creating WAR target/foo-2.5.3.war 
MacBook-Air:foo mba$ md5 target/foo-2.5.3.war 
MD5 (target/foo-2.5.3.war) = 157635f7d152cb56bc3b5bd731a8fb6e 

不改变的事情，我所做的连续被运行相同grails test war命令两次。从第二次运行生成的WAR文件具有与第一次不同的MD5校验和。任何人都可以帮我理解为什么？我运行Grails 2.5.0是值得的。

Answer 1

当Grails生成战争时，它会使用默认应用程序（grails create-app foo - >grails war）在多个位置插入或更新时间戳。

有在时间戳：

• application.properties
• views.properties
• manifest.properties

此外，在一些属性文件的字符串的顺序没有保证，因此一些线路出现在后续运行中以不同顺序排列。
