ant 优化android 项目编译第二波，simple编译项目只需1分钟

 由于第一次的脚本在改动java文件后仍需约五分钟，现进行第二次优化，

上片请进 http://liuqzan.iteye.com/blog/951995

 

 

 

分析：编译耗时主要在资源文件引用的生成和资源文件的打包与二进制处理流程中

对于一个只修改了java文件的项目而言，无需重新执行资源文件的打包与二进制流程

上一个ant 在只修改了java文件的时候编译仍需5mins因为重复生成 二进制 资源文件，此步可以在没有资源文件更改的情况下，只需执行过一次，以后编译时可以省去

 

 

ant 脚本优化生成三个功能：

1：generate R:   更新R文件 耗时约4mins

2：package-resources   : 在有资源文件改变的情况下打包生成资源文件，耗时约4 mins

3：simple： 在没有资源文件改变，只改变的JAVA相关文件，且之前执行过一次package-resources ，生成apk只需一分钟。

 

针对以前三种开发情境,现在处理：

在资源文件更改, 不用生成apk，只需要使用资源引用的情况(5%) ：使用命令 ant generateR 只更新R文件 耗时 约4mins

更新了资源文件，又修改了JAVA文件想立即生成apk，(5%) 则联合使用:ant generateR à  ant package-resources à ant  simple  约10mins

频繁修改java类文件，资源文件不变，只需要生成apk(90%):使用命令ant simple  ,耗时约  1mins

 

优点：

可操作性强，三个处理流相互独立，处理时互不影响 。

节约时间，定制编译

 

缺点：需要手动使用ant 命令

旧版的ANTTASK.JAR与新版的ANT-TASK.JAR 不一样的，所以在使用新版的SDK TOOLS时会出现1，2楼的错

BUILD FAILED
test.xml:46: taskdef class com
.android.ant.SetupTask cannot be found
using the classloader AntClassLoader[]

请问这个是什么地方需要配置么？ 本机sdk没有发现对应的jar包

你好，下面这个错误是什么地方没有配置引起的吗？

D:\project\GameWorkspace\antTest\build.xml:465: Reference android.libraries.src not found.
