Maven浅析-3 Ant Vs Maven

1.什么是Ant？

Ant起源是为了取代构建工具Make。它可以跨系统，建立在Java和XML的基础上，而且非常程式化。

Ant更像一个脚本工具，我们必须在Ant内显示地声明做任何事情。在<target>内声明，而且没有统一的标准，一个application可能会包含庞大的repository。

2. Maven

Maven不仅仅是一个脚本工具，它更是一个成熟的构建工具。它有很多隐式的功能，譬如一致性，继承，transitive dependencies，版本管理。

3.优点和缺点<待完善>

Maven：

Maven can be a black box.

steeper learning curve

convertion over configuration

Better IDE integration

Less overheard through use of repos

different mindset, steepest learning curve is not making maven act like Ant

Ant：

we can trace Ant files fairly easily

quicker to learn, but very copy-paste intensive

larger project size in SCM, artifacts stored with project

e.g. Ant build.xml

　　</target>

　　</target>

　　　　　　</manifest>

　　　　</jar>

　　</target>

　</target>

</project>

e.g. Maven pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"

　　　　xmlns:xsi="http://www.x.org/xx/xxy"

　　　　xsi:schemalocation="xx">

　　<groupId>com.dahang</groupId>

　　<artifactId>HelloWorld</artifactId>

　　<version>0.0.1-SNAPSHOT</version>

</project>

5.Summary:

Ant is very declarative.

Maven follows a convention over configuration model

Ant may be easier to learn, but it really is only beneficial as a scripting tool.

Maven is really centered around managing your entire project's lifecycle.
