ant 条件判断 condition(转)

用ant写个build.xml，用到condition，作笔记如下：

basicelements:istrueisfalsenotandorxoravailableissetequalsfilesmatch

1、istrueisfalse:断言真假

<projectname="testCondition">

<targetname="test">

<conditionproperty="scondition">

<istruevalue="true"/>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

2、逻辑运算

2.1、not逻辑非

<projectname="testCondition">

<targetname="test">

<conditionproperty="scondition">

＜not>

<istruevalue="true"/>

</not>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

2.2、and逻辑与

<projectname="testCondition">

<targetname="test">

<conditionproperty="scondition">

＜and>

<istruevalue="true"/>

<istruevalue="false"/>

</and>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

2.3、or逻辑或xor异或(语法上与and类似)

3、available是否可用

<projectname="testCondition">

<pathid="all.test.classes">

<pathelementlocation="bin"/>

</path>

<targetname="test">

<conditionproperty="scondition">

<!--在指定的classpath路径下是否存在资源TestTest.class-->

<availableresource="TestTest.class">

<classpathrefid="all.test.classes"/>

</available>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

4、isset指定属性是否存在

<projectname="testCondition">

<!--属性也可以通过ant参数-D来设置-->

<propertyname="name"value="thisisname"/>

<targetname="test">

<conditionproperty="scondition">

<!--如果属性name不存在则返回false-->

<issetproperty="name"/>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

5、equals是否相等

<projectname="testCondition">

<!--属性也可以通过ant参数-D来设置-->

<propertyname="name"value="thisisname"/>

<targetname="test">

<conditionproperty="scondition">

<!--如果arg1的值与arg2的值相等返回true，否则为false-->

<equalsarg1="${name}"arg2="thisisname"/>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>

6、filesmatch比较文件

<projectname="testCondition">

<targetname="test">

<conditionproperty="scondition">

<!--如果file1所代表的文件与file2所代表的文件相等返回true，否则为false-->

<filesmatchfile1="testfile1.txt"file2="testfile2.txt"/>

</condition>

<antcalltarget="isTrue"></antcall>

<antcalltarget="isFalse"></antcall>

</target>

<targetname="isTrue"if="scondition">

<echo>isture</echo>

</target>

<targetname="isFalse"unless="scondition">

<echo>isfalse</echo>

</target>

</project>
