Read <property> value from file within build.xml

Question

Can I read the the property value from an external file instead of specifing the value within the <property> tag.

So instead of -

 <property name="device" value="test" />

Use something like

 <property name="device" value="c:\\fileToRead" />

where file to read contains test,test2,test3

Thanks

Answer 1

<property>任务提供了一种加载Java属性文件的方法，如果您的意思是这样的话：

<property file="c:\\fileToRead"/>

Answer 2

Maybe. While you can't use the content of the file, you can use a file that looks like so:

device=C:\\fileToRead

and then read that with

<property file="foo.properties"/>

( see the docs ).

Answer 3

in build.xml

<property file="general.properties" />

general.properties file

svnant.version=1.0.0
lib.dir=${ant.home}/lib

So for you will be:

<property file="c:\\fileToRead" />

fileToRread is

 device=test
