在Java或ANT下的regexp中輸出換行符

Question

我有調用replaceregexp任務的ant目標

<target name="regexp.replace">
    <replaceregexp file="${file.temp}"
                   match="(.*)"
                   replace="first operation on \1  second operation on \1"
                   byline="true"/>
</target>

file.temp是

A1
A2

期望的輸出是

first operation on A1
second operation on A1
first operation on A2
second operation on A2

在ant replaceregexp參數中插入新行char以生成所需輸出的內容？

 replace="first operation on \1 %NEW_LINE% second operation on \1"

Answer 1

以下適用於我：

<replaceregexp file="test.txt"
               match="(.*)"
               replace="first operation on \1${line.separator}second operation on \1"
               byline="true"/>
