So, I am trying to code a regular Java application which reads the current revision from a file which is updated by ANT during compile time. When run on my dev machine (Eclipse 3.5.2 on Ubuntu 11.04) with either the OpenJDK or SunJDK, it throws a FileNotFoundException. Adding or removing a leading backslash seems to have no effect.
Any ideas on how I could solve this? I believe the fault lies in this line here:
in = new FileInputStream("data/build_info.properties");
String revision = "";
Properties defaultProps = new Properties();
FileInputStream in;
try {
in = new FileInputStream("data/build_info.properties");
defaultProps.load(in);
in.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
revision = "Version: " + defaultProps.getProperty("build.major.number") + "." +
defaultProps.getProperty("build.minor.number") + " " +
"Revision: " + defaultProps.getProperty("build.revision.number");
<target name="jar">

If you're trying to load a file inside of the Jar, then you need to use java.lang.Class.getResourceAsStream() to load the file. You can't point to a file that's in the Jar with java.util.File. For an example on how to use it, see this answer:
