我想在我的maven构建中包含一个版本文件，这样每个构建都会自动增加构建号，并在我的程序集中包含一个版本文件：
<major>.<minor>.<buildNo> 1.0.2 --> 1.0.3 //include this in version.txt
目前，我正在使用插件autoincrement-versions-maven-plugin自动增加pom文件中的版本;该部分有效，但当我过滤version.txt时，在我的程序集中以及target/classes中结束的文件具有旧版本号。
Maven不允许对<properties>中定义的值进行动态更新，所以我理解为什么这不起作用（我认为），那么替代方案是什么？我可以用GMaven插件破解它，但是必须有一个更简单的方法。

不是最性感的解决方案，但效果很好。这种方法不使用上面提到的自动增量插件，也不使用version.txt的资源过滤;相反，Groovy控制着一切。另外一个好处是，版本信息从pom外部化到build.properties，这有助于在这种情况下使用Groovy。
fullVersionNumber=1.0.6
versionNumber=1.0
buildNumber=6
import java.nio.file.*
def version = project.properties['proj.version']
def build = project.properties['proj.build']
if(build?.isNumber()){
build = build as Integer
build++
Properties buildProps = new Properties()
buildProps.setProperty('buildNumber', build.toString())
buildProps.setProperty('fullVersionNumber', version + '.' + build)
buildProps.setProperty('versionNumber', version.toString())
Path buildFile = Paths.get('./build.properties')
Path assemblyBuildFile = Paths.get('./target/classes/build.properties')
File propsFile = new File(buildFile.toUri())
Writer writer = null
try{
//update build.properties
writer = propsFile.newWriter()
buildProps.store(writer, null)
//copy for assembly
Files.copy(buildFile, assemblyBuildFile)
}catch(Exception e){
throw new RuntimeException(e)
}finally{
if(writer) writer.close()
}
}else{
throw RuntimeException('Invalid build number: ' + build)
}
