Using NetBeans to work on the langtools repository.+
−
+
−
Netbeans 6.0 or later is recommended.+
−
+
−
The "langtools" project in this directory allows you to+
−
edit, run, test and debug the tools in the OpenJDK langtools+
−
repository.+
−
+
−
The repository contains a number of tools:+
−
    apt, javac, javadoc and its doclets, javah and javap.+
−
+
−
Build Properties.+
−
+
−
To build this repository, you must set some properties for Ant.+
−
You can set these properties in a number of ways:+
−
+
−
- Set the properties in the Properties panel under Tool> Options> Ant.+
−
  Properties set this way will apply globally to all the langtools +
−
  repositories you may be working on.+
−
+
−
- Create a file build.properties in the root directory of a+
−
  langtools repository, and set the properties in that file.+
−
  These properties will be specific to that repository.+
−
+
−
To build the repository, at a minimum you must set the "boot.java.home"+
−
property.  To run the tools, you must also set "target.java.home". To+
−
run the regression tests, you must set "jtreg.home".+
−
+
−
By default, the build and test targets will build and test all+
−
of these tools. The run and debug targets will prompt you for the+
−
name of a tool to execute.+
−
+
−
As an alternative, you can focus on a single tool.  When you do+
−
this, you will still see all the source code for all the tools,+
−
but the various Ant targets will now be focussed on the selected tool.+
−
To focus on a tool, bring up the context menu on the "langtools"+
−
project (i.e. right-click on the project) and select "Select Tool".+
−
This brings up a dialog which allows you to specify which tool you+
−
wish to work on, and the arguments to use if and when you run it.+
