Auto Increment Build/Version Number

[rwmorey]

Hi --



I am new to Java/NetBeans programming and I am wondering if there is a way to access a build number for my project from within the project and to also have this number auto increment each time I compile my project.



If so, can someone provide me guidance with how to access the build number as well as setting it to auto-increment?



Thanks

Hi Rich,

try this:

1) Add the following code to yout build.xml


<target name="-pre-jar" >
<propertyfile file="${src.dir}\version.properties">
<entry key="BUILD" value="1" type="int" operation="+"/>
</propertyfile>
</target>

2) create a file named 'version.properties' in your sources directory
and put a 'BUILD=0' into it (without quotes )

Now each successfully compilation of you app will increase the
buildnumer in the property-file

To acces the build number from witihin you app add something like this
to your app (e.g. in Class Main):


final static ResourceBundle rb =
ResourceBundle.getBundle("version.properties");

public static final String getRbTok(String propToken) {
String msg = "";
try {
msg = rb.getString(propToken);
} catch (MissingResourceException e) {
System.err.println("Token ".concat(propToken).concat(" not
in Propertyfile!"));
}
return msg;
}

Now you can acces your build-Number quit simple:

System.out.println("This is build %s", getRbTok("BUILD"));


Good Luck,
Andreas

If you are using version control a better approach would be to run the
svnversion tool on the top-level of your source tree and parse the first
number returned (it may return a single number or a number followed by a
colon and another number).

I'm working with CVS. Can I do what you're saying from within the code. I
haven't tried the first option yet. But wont it be a problem with the CVS.

Thank you for this info. I added the lines to my BUILD.XML file but this line:



final static ResourceBundle rb =

ResourceBundle.getBundle("version.properties");



is throwing an exception. It also does not appear that the BUILD= value is being incremented. I have put the version.properties file in the \projectname\src\ directory.



Any ideas? Is the file not in the correct location? Can I 'hard' code the directory just to make sure the incrementing part is working?



Thanks

Ok, I changed the target name="" to "-pre-compile" and copied the file into \src\java\ and now the incrementing is working.



Still working on getting the value.

Still can't get this to work. The error is



Can't find bundle for base name version.properties



I'm guessing I have to do something to put this value inside the Java and thats why it was tagged as -pre-jar ?



Thanks

The base name should be without the extension ".properties", i.e. just
"version".

Hi,
If you change the ant-target from "-pre-jar "to "-pre-compile" you
increase the build number each time you start a compile - althoug the
compilation fails. When using -pre-jar it should only increase on
successfull compilation.

Can't find bundle: As Marián said, remove '.properties' extension in getBundle()-call. (Sorry 4 that)

Thanks! I made that change and it worked.
