需要Ant脚本来替换字符串

Question

示例：test.txt

hello:../../Need/script/hello/123/234
hello:../../../../Need/script/hello/123/468
hello:../Need/Script/hello/123/789

需要使用此字符串替换“hello”字词：“：D：/ test / testing / tester /”

输出：test.txt

hello:D:/test/testing/tester/hello/123/234
hello:D:/test/testing/tester/hello/123/468
hello:D:/test/testing/tester/hello/123/789

尝试了类似下面的脚本，但是遇到了java错误。

<replaceregexp file="./test.txt"
               match="hello**hello"
               replace="hello:D:/test/testing/tester/hello"
               byline="true"/>

错误：
