如何在Eclipse中开发并调试自己的插件（或者说如何将自己的代码插件化）

Setting up Eclipse to create and debug plugins for ImageJ

最近在做一个关于卫星遥感全链路仿真的项目，由于项目是基于ImageJ开发，而ImageJ提供了强大的插件机制，所以特来写一个东西说明如何将自己的代码转化为ImageJ的插件。

• Alt-File –> New
• Select the Java Project wizard and click Next

• Project name: IJ. Check Create separate folders for sources and class files. Click Next

• On the following panel, select Source tab and check if Default output folder is set to IJ/bin

• On the Libraries tab click on Add external JARs, browse to your Java SDK library folder , select tools.jar, click Ok and click on Finish to create the project.

(on my computer the Java SDK library folder is located at C:\Program Files\Java\jdk1.6.0_02\lib)

• Finally, get the latest copy of ij here, extract the zip
• Copy the ij folder and its subfolders into the source folder
• Copy the images, macros and plugins folder and only IJ_Props.txt to the IJ project root.
• Click on F5 to tell Eclipse to refresh its Package list

Create a new plugin (or import your previously developed plugins).

• Alt-File –> New
• Select the Java Project wizard and click Next

• Give your plugin a name (don‘t forget to add an underscore if you want it to appear in the ImageJ menu!)

• On the Source tab, check that the output folder is set TestPlugin_/bin

• On the Project tab, click Add… and select your previously created IJ project containing the ImageJ source.
• Click Finish

• Create your Java plugin files. In our example, I created a sample TESTPlugin_.java with the following content:

import ij.IJ;

import ij.plugin.PlugIn;

public class TestPlugin_ implements PlugIn {

    public void run(String arg) {

        IJ.error("Hello world!");

    }

}

• Create a file called build.xml in the project root folder. A sample build.xml file follows, which you should adapt to your needs.

<project name="TESTPlugin_" default="" basedir=".">

<description>

TESTPlugin_ build file

</description>

<property name="src" location="src" />

<property name="build" location="bin" />

<property name="dist" location="dist" />

     <property name="pluginsDir" location="$basedir/../../IJ/plugins/" />

<property name="user.name" value="Patrick Pirrotte" />

<target name="main" depends="compress" description="Main target">

    <echo>

        Building the .jar file.

    </echo>

</target>

<target name="compress" depends="" description="generate the distribution">

    <jar jarfile="TESTPlugin_.jar">

        <fileset dir="." includes="plugins.config" />

        <fileset dir="${build}" includes="**/*.*" />

        <manifest>

                   <attribute name="Built-By" value="${user.name}"/>

        </manifest>

    </jar>

<copy file="TESTPlugin_.jar" toDir="${pluginsDir}" />

</target>

</project>

• In the Package Explorer, right click on the TESTPlugin_ project, click on Properties, select Builders, click New… and select Ant Builder

• In the Main Tab, click Browse workspace and select the build.xml from your TESTPlugin_ project.

• In the Targets tab, click Set Targets for both After clean and Auto build targets, and select both main and compress.
• Click Ok twice to keep your changes.

• Goto Run→ Debug Configurations and create a new Java Application Debug Configuration. Fill in IJ In the field Project, and ij.ImageJ in the field Main class.

• Select the Source tab, then in the Source lookup path, Add→Add Java Project. Select the TestPlugin_ project. This step is crucial if you want to step into your plugin source during the debug phase. Apply the changes.

• If you select Debug, ImageJ will start and your TESTPlugin_ will show up in the Plugins menu…
• Set breakpoints in plugins or in the ImageJ source, the debugger should break accordingly.

后注：当然上文只是其中一种方法，也还有其他方法可以实现！！！
