一、概述

??? 需要設置的環境變量：
??? ??? JAVA_HOME="D:\JDK",
??? ??? ANT_HOME="D:\ant",
??? ??? PATH=".,%JAVA_HOME%\bin,%ANT_HOME%bin"
??? 運行：ant -buildfile test.xml -Dbuild=build/classes dist
（含義為：執行test.xml的編譯腳本，參數build的值為build/classes，要執行的target為dist）
??? 默認的編譯腳本為build.xml，默認的target為編譯腳本中的project的default屬性值所對應的target

二、常用task

??? 編譯腳本是xml文檔，元素有project->target->task，property,filter。
(右擊前面查看圖片)
??? task有內置的和可選的之分，可選task需要下載額外的包來支持，此外可以編寫自己的task。

1、Echo????

Parameters

Attribute	Description	Required
message	the message to echo.	Yes, unless data is included in a character section within this element.
file	the file to write the message to.	No
append	Append to an existing file?	No - default is false.
level	Control the level at which this message is reported. One of "error", "warning", "info", "verbose", "debug"	No - default is "warning".

Examples

<echo message="Hello, world"/>

<echo message="Embed a line break:${line.separator}"/>

<echo>Embed another:${line.separator}</echo>

<echo>This is a longer message stretching over
two lines.
</echo>

2、Javac

Parameters（not all）

Attribute	Description	Required
srcdir	Location of the java files. (See the note below.)	Yes, unless nested <src> elements are present.
destdir	Location to store the class files.	No
includes	Comma- or space-separated list of files (may be specified using wildcard patterns) that must be included; all .java files are included when omitted.	No
includesfile	The name of a file that contains a list of files to include (may be specified using wildcard patterns).	No
excludes	Comma- or space-separated list of files (may be specified using wildcard patterns) that must be excluded; no files (except default excludes) are excluded when omitted.	No
excludesfile	The name of a file that contains a list of files to exclude (may be specified using wildcard patterns).	No
classpath	The classpath to use.	No
sourcepath	The sourcepath to use; defaults to the value of the srcdir attribute (or nested <src> elements). To suppress the sourcepath switch, use sourcepath="".	No

Examples

<javac srcdir="${src}"
         destdir="${build}"
         includes="mypackage/p1/**,mypackage/p2/**"
         excludes="mypackage/p1/testpackage/**"
         classpath="xyz.jar"
         debug="on"
  />

3、jar

Parameters（not all）

Attribute	Description	Required
destfile	the JAR file to create.	Yes
basedir	the directory from which to jar the files.	No
compress	Not only store data but also compress them, defaults to true. Unless you set the keepcompression attribute to false, this will apply to the entire archive, not only the files you've added while updating.	No
keepcompression	For entries coming from existing archives (like nested zipfilesets or while updating the archive), keep the compression as it has been originally instead of using the compress attribute. Defaults false. Since Ant 1.6	No
encoding	The character encoding to use for filenames inside the archive. Defaults to UTF8. It is not recommended to change this value as the created archive will most likely be unreadable for Java otherwise.	No
filesonly	Store only file entries, defaults to false	No
includes	comma- or space-separated list of patterns of files that must be included. All files are included when omitted.	No
includesfile	the name of a file. Each line of this file is taken to be an include pattern	No
excludes	comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted.	No
excludesfile	the name of a file. Each line of this file is taken to be an exclude pattern	No
defaultexcludes	indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted.	No
manifest	the manifest file to use. This can be either the location of a manifest, or the name of a jar added through a fileset. If its the name of an added jar, the task expects the manifest to be in the jar at META-INF/MANIFEST.MF	No

Examples

<jar destfile="${dist}/lib/app.jar"
??? basedir="${build}/classes"
??? includes="mypackage/test/**"
??? excludes="**/Test.class" />

<jar destfile="${dist}/lib/app.jar">
??? <fileset dir="${build}/classes"
??? ??? ??? excludes="**/Test.class" />
???? <fileset dir="${src}/resources"/>
</jar>

4、javadoc

Parameters（not all）

Attribute	Description	Availability	Required
sourcepath	Specify where to find source files	all	At least one of the three or nested <sourcepath>, <fileset> or <packageset>
sourcepathref	Specify where to find source files by reference to a PATH defined elsewhere.	all
sourcefiles	Comma separated list of source files -- see also the nested source element.	all
