在 Ant 中传递分号作为参数 [英] Pass semicolon in Ant as a parameter
问题描述
我想通过";;;"字符串作为我 Ant 任务中的字符串参数:
I want to pass ";;;" string as a string parameter in my Ant task:
<mytask param=";;;"/>
但 Ant 将分号视为特殊符号并引发错误
but Ant consider semicolon as a special symbol and raises an error
java.lang.IllegalArgumentException:非法组引用
我怎么逃跑;将它传递给 Ant 的符号?
how can I escape ; symbol to pass it to Ant?
附言我还发现我不能通过 { 符号,
所以我想知道在 Ant 中转义字符的常用方法是什么?
我试过$;$;$;"但它对我不起作用
p.s. also I found that I can't pass { symbol,
so I wonder what's the common way to escape characters in Ant?
I've tried "$;$;$;" but it's not working for me
更新:示例代码:
public class MyTask extends Task {
private String value;
public void setValue(String value) {
this.value = value;
}
public void execute() {
System.out.println(value);
}
}
和蚂蚁任务:
<taskdef name="mytask" classpath="build/lib/CustomTasks.jar"
classname="MyTask"/>
<mytask value=";;;"/>
推荐答案
我对这个示例没有任何问题:
I have not any problem with this sample:
<target name="test_passing_params">
<antcall target="test_echo">
<param name="param1" value=";;;"/>
<param name="param2" value="{"/>
</antcall>
</target>
<target name="test_echo">
<echo>param1: ${param1}</echo>
<echo>param2: ${param2}</echo>
</target>
输出:
回声
参数 1: ;;;
回声
参数 2:{
echo
param1: ;;;
echo
param2: {
mytask
任务的实现可能有问题?
May be problem in implementation of mytask
task?
