Encode QR In Java
Using Barcode generation for Java Control to generate, create QR Code 2d barcode image in Java applications.
Sometimes, different developers using different versions of Eclipse want to work on the same project If the project in question does not involve any Eclipse plug-ins, then there is no problem The problem arises when a project uses the ECLIPSE_HOME classpath variable, which is automatically managed by the environment to point to the current Eclipse installation As a result, any project using ECLIPSE_HOME references plug-ins in the current Eclipse installation For example, a developer using Eclipse 34 will have the project compiled against the Eclipse 34 plug-ins, whereas someone using Rational Application Developer 70, which is based on Eclipse 32, will have that same project compiled against Eclipse 32 plug-ins One solution is to use the PDE Target Platform preference page (see Figure 19 9) Using this page, you can retarget the ECLIPSE_HOME classpath variable at a different Eclipse installation The problem with this approach is that it does not address the problem of different projects compiled against different versions of Eclipse With this solution, you will have all projects compiled against the same Eclipse installation

Another solution is to never use the ECLIPSE_HOME classpath variable at all Assuming that you want to support Eclipse 32, 33, and 34, install all three Eclipse versions into separate directories with names such as c:\eclipse32, c:\eclipse33, and c:\eclipse34 Then, set up three classpath variables named ECLIPSE32_HOME, ECLIPSE33_HOME, and ECLIPSE34_HOME, which point to their respective Eclipse installations If a project has been compiled against Eclipse 34, you would use ECLIPSE34_HOME rather than ECLIPSE_HOME With this approach, it doesn t matter which version of Eclipse is being used as the code is always compiled against one specific Eclipse version The downside of this approach is that the PDE will not keep the plug-in manifest dependency list in sync with the project s classpath file

During the PDE Build process, a buildxml file is generated for each feature and plug-in being compiled and assembled To assist in understanding and debugging the PDE Build process, the PDE Tools can generate buildxml files identical to the ones generated during the PDE Build process In the Navigator view, right-click on a featurexml or pluginxml file and select PDE Tools > Create Ant Build File

These auto-generated build scripts are a bit complicated, containing five external targets and seven internal targets (see Figure 19 10) The zipplugin and buildupdatejar targets call other targets, and all the targets depend on the init target, which in turn depends on the properties target Because these files are generated as part of the PDE Build process, you would not manually edit them and they should not be checked into a source code management system Instead, to add custom operations, use the PDE Build callbacks (see Section 19211, Custom PDE Targets, on page 723)

The Eclipse Debugging Environment for Java is very useful, and the same capability exists for debugging Ant scripts and the PDE Build process You can set breakpoints, step through scripts, and inspect variables Follow the following steps to debug the build-favoritesxml Ant script:

You must be using Java 15 or later Import the PDE Build plug-in as linked binary project by switching to Plug-ins view, right-clicking on orgeclipsepdebuild plug-in and selecting Import As > Binary Project with Linked Content Switch back to the Package Explorer view, right click on the buildfavoritesxml Ant script, and select Debug As >Ant Build When the Edit Configuration dialog appears, click the JRE tab and select the Run in the same JRE as the workspace checkbox Click Debug to execute the Ant script (see Figure 19 11) You may notice occassional quirks such as breakpoints in callback not stopping execution If a breakpoint does not seem to be working, try setting a breakpoint in a higher level file or in the top level build script, and then stepping down into the callback
