来源：互联网发布：mac系统pdf转换成word 编辑：程序博客网时间：2024/05/16 12:14

1重命名

<rename dest="ant-${version}.jar" src="foo.jar" />

2修改文件时间，也可以判断文件是否存在

<touch file="build.xml" datetime="06/06/2000 2:02 pm"></touch>

3条件语句

<?xml version="1.0"?><project name="filemanager" default="outputXML"><target name="outputXML"><condition property="ifexist"><istrue value="true"/></condition><antcall target="istrue"></antcall><antcall target="isfalse"></antcall></target><target name="istrue" if="ifexist"><echo>${ifexist}</echo></target><target name="isfalse" unless="ifexist"><echo>${ifexist}</echo></target></project>

4condition

istrue isfalse:断言真假

<target name="test">          <condition property="scondition">              <istrue value="true"/>                              </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>

not 逻辑非

<target name="test">          <condition property="scondition">              ＜not>                  <istrue value="true"/>                                  </not>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>

and 逻辑与

 <target name="test">          <condition property="scondition">              <and>                  <istrue value="true"/>                  <istrue value="false"/>                                  </and>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>

available 是否可用

<path id="all.test.classes">                    <pathelement location="bin"/>       </path>      <target name="test">          <condition property="scondition">              <!--在指定的classpath路径下是否存在资源 TestTest.class-->              <available resource="TestTest.class">                  <classpath refid="all.test.classes" />                      </available>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>

isset 指定属性是否存在

<project name="testCondition" default="test">      <!--属性也可以通过ant参数-D来设置-->      <property name="name" value="this is name"/>          <target name="test">          <condition property="scondition">              <!--如果属性name不存在则返回false-->              <isset property="name"/>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>  </project>

equals 是否相等

<project name="testCondition">      <!--属性也可以通过ant参数-D来设置-->      <property name="name" value="this is name"/>          <target name="test">          <condition property="scondition">              <!--如果arg1的值与arg2的值相等返回true，否则为false-->              <equals arg1="${name}" arg2="this is name"/>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>  </project>

filesmatch 比较文件

<project name="testCondition">              <target name="test">          <condition property="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-->              <filesmatch file1="testfile1.txt" file2="testfile2.txt"/>          </condition>          <antcall target="isTrue"></antcall>          <antcall target="isFalse"></antcall>              </target>      <target name="isTrue" if="scondition">          <echo>is ture</echo>      </target>      <target name="isFalse" unless="scondition">          <echo>is false</echo>      </target>  </project>
