Apache Ant：4:容器方式的Ant构建

这篇文章通过一个具体的示例来介绍如何进行容器方式的Ant构建。

事前准备

• 获取Ant构建镜像

执行命令：docker pull liumiaocn/ant:1.10.7

• 获取Ant构建的示例代码

执行命令：git clone http://github.com/liumiaocn/easypack

构建示例代码说明

[root@liumiaocn ~]# git clone http://github.com/liumiaocn/easypack.git

[root@liumiaocn ~]# cd easypack/ant/
[root@liumiaocn ant]# cd demo
[root@liumiaocn demo]# ls
build.xml  HelloWorld.java
[root@liumiaocn demo]# cat HelloWorld.java 
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World, LiuMiao");
    }
}
[root@liumiaocn demo]# 
[root@liumiaocn demo]# cat build.xml 
[root@liumiaocn demo]#

构建

缺省会在/data目录下，因为此目录下有build.xml文件的存在，所以可以直接使用ant jar进行构建即可。

liumiaocn:demo liumiao$ pwd
/Users/liumiao/easypack/ant/demo
liumiaocn:demo liumiao$ ls
HelloWorld.java	build.xml
liumiaocn:demo liumiao$ docker run --rm -v `pwd`:/data liumiaocn/ant:1.10.7 ant jar
Buildfile: /data/build.xml

build:
    [mkdir] Created dir: /data/classes
    [javac] Compiling 1 source file to /data/classes

jar:
      [jar] Building jar: /data/hello.jar

BUILD SUCCESSFUL
Total time: 1 second
liumiaocn:demo liumiao$ ls
HelloWorld.java	build.xml	classes		hello.jar
liumiaocn:demo liumiao$ java -jar hello.jar 
Hello World, LiuMiao
liumiaocn:demo liumiao$

也可以使用-f选项指定构建文件进行ant的target执行

liumiaocn:demo liumiao$ docker run --rm -v `pwd`:/data liumiaocn/ant:1.10.7 ant -f /data/build.xml clean
Buildfile: /data/build.xml

clean:
   [delete] Deleting directory /data/classes
   [delete] Deleting: /data/hello.jar

BUILD SUCCESSFUL
Total time: 0 seconds
liumiaocn:demo liumiao$ ls
HelloWorld.java	build.xml
liumiaocn:demo liumiao$
