How to put a newline in ant property
提问by Yoni
This doesn't seem to work:
这似乎不起作用：
<property name="foo" value="\n bar \n"/>
I use the property value in the body of an e-mail message (which is sent as plain text):
我在电子邮件消息的正文中使用属性值（以纯文本形式发送）：
<mail ...>
<message>some text${foo}</message>
and I get literal "\n" in the e-mail output.
我在电子邮件输出中得到文字“\n”。

These all work for me:
这些都对我有用：
<property name="foo" value="bar${line.separator}bazz"/>
<property name="foo">bar
bazz2</property>
<property name="foo" value="bar bazz"/>

You want ${line.separator}. See this postfor an example. Also, the Ant echo taskmanual page has an example using ${line.separator}.
你要${line.separator}。有关示例，请参阅此帖子。此外，Ant echo 任务手册页有一个使用${line.separator}.
By using ${line.separator}you're simply using a Java system property. You can read up on the list of system properties here, and here is Ant's manual pageon Properties.
通过使用，${line.separator}您只是在使用 Java 系统属性。您可以在这里阅读系统属性列表，这里是 Ant 的属性手册页。
