* You can also use ant's built-in attributes, such:
The absolute path of the basedir project base Directory (same as the basedir attribute of <project> ).
The absolute path of ant. File buildfile.
Ant. Version ant version.
The name of the project currently executed by Ant. Project. Name is set by the name attribute of <project>.
The JVM Version Detected by Ant. java. Version ant. The current value is "1.1", "1.2", "1.3" and "1.4 ".
;
1. Use-DVAR = value to specify or modify the property value at runtime.
<? XML version = "1.0" encoding = "UTF-8" ?>
< Project Basedir = "." Default = "Test" Name = "Testproject" >
< Property Name = "Var1" Value = "Value1" />
< Property Name = "Var2" Value = "Value2" />
< Target Name = "Test" Description = "Test property overwrite" >
< Echo Message = "Var1 =$ {var1 }" />
< Echo Message = "Var2 =$ {var2 }" />
</ Target >
</ Project >
Run ant:
Test:
[Echo] var1 = value1
[Echo] var2 = value2
Run ant-dvar1 = value1new:
Test:
[Echo] var1 = value1new
