Question

What i want :

Generate jar file with apps version in name, Ex : MyApps-1.3_Beta.jar

In my src folder , i have a file named “version.properties” which contain :

…
apps=MyApps
apps.version=1.3_Beta
…

i need to change value of property “dist.jar” to something like this :

dist/${apps}-${apps.version}.jar

build.xml :

<?xml version="1.0" encoding="UTF-8"?>
<project name="MyApps" default="default" basedir=".">
  <description>Builds, tests, and runs the project MyApps.</description>
  <target name="-pre-init">
      <property file="${src.dir}\MyApps\version.properties"/>
      <property name="dist.jar" value="dist/${apps}-${apps.version}.jar" />
   </target>
  <import file="nbproject/build-impl.xml"/>
  <import file="nbproject/profiler-build-impl.xml"/>
  <echo level="info">${dist.jar} instead of dist/${apps}-${apps.version}.jar</echo>
</project>

Echo output :

dist/${apps}-${apps.version}.jar instead of dist/MyApps-1.3_Beta.jar

The problem is that ${…} is not interpreted, and i don’t know why.

I can’t modify “build-impl.xml” because it can be regenerate by Netbeans (When i modify this file (all ${dist.jar}), it works but it’s not a good solution).

How can i change “dist.jar” property ?

NB: it’s not a problem if for change “dist.jar” I’m not using “project.properties”, project name and apps name can be different, but for “dist” folder it will be better to use it

It looks like you’re not reading the properties file you want. Run Ant with the -verbose arg and you may see something like:

[property] Loading src\MyApps\version.properties
[property] Unable to find property file: src\MyApps\version.properties

(In the text you say the properties file is in the src directory, but the buildfile is looking for it in src\MyApps.)
