Subject RE: how to change the property value at run time
Date Wed, 14 May 2008 15:16:09 GMT
You can set java_home at runtime in windows. If you're compiling multiple projects with two
version of java it is best not to set java_home as environment variable. 

There are multiple ways of achieving the same outcome...here are two ideas.

First, set java_home in a batch file to kick-off the build process and set java home. Create
a .bat file and add the following content.
set JAVA_HOME=<to directory path of java>
call ant -f build.xml

Second, create a build.properties in the same directory as build.xml and add the following
content.
java.home = <to directory path of java>

Remember to load the properties file in your build.xml i.e. <property file="build.properties"/>

Hope this helps.

Thats just the special thing about ANT-properties: You can not change them, for good reasons.

But JAVA_HOME does not look like an Ant-property. What do you want to do?

Betreff: how to change the property value at run time

Hi All,

 

I need to change the value of a specific property at run time. Can somebody please let me
know how I can do that.

 

Let's say the property name is "JAVA_HOME" and suppose I want to change the value of that
property to "d:\install"

 

Please help.

 

Regards,

Irfan
