在Eclipse中，如何以编程方式在Classpath条目中设置JavaDoc URL？ [英] In Eclipse, how to set JavaDoc URL on a classpath entry programmatically?

问题描述

我有一个Eclipse插件，除其他外，可以创建一个项目并给它几个类路径条目。这本身就可以正常工作。

这些jar没有包含源代码，但是有一个可以用于Javadoc的URL。我想通过插件创建的这些类路径条目以编程方式设置。这是我在做的：

  IClasspathEntry cpEntry; 
 
文件[] jarFile = installFilePath.listFiles（）; 
 
 IPath jarFilePath; 
（int fileCount = 0; fileCount< jarFile.length; fileCount ++）
 {
 jarFilePath = new Path（jarFile [fileCount] .getAbsolutePath（））; 
 cpEntry = JavaCore.newLibraryEntry（jarFilePath，null，null）; 
 entries.add（cpEntry）; 
} 
  

我无法弄清楚如何在claspath条目中设置JavaDoc URL位置。这可以在Eclipse UI中完成 - 例如，如果右键单击项目，请转到属性 - >Java构建路径，然后展开其中一个JAR条目并编辑Javadoc位置，您可以指定一个URL。如何从插件中执行此操作？

解决方案

我使用以下内容：

 路径pth =新路径（MY_JARFILE_LOCATION）; 
路径pthd =新路径（MY_JAVADOC_LOCATION）; 
 ClasspathAttribute att = new ClasspathAttribute（javadoc_location，file：+ pthd.toOSString（））; 
 IClasspathAttribute [] atts = new IClasspathAttribute [] {att}; 
 IClasspathEntry cpISDI = JavaCore.newLibraryEntry（pth，null，null，null，atts，false）; 
 cpEntries.add（1，cpISDI）; 
  

（编辑格式）

I have an Eclipse plugin, that among other things, can create a project and give it several classpath entries. This in and of itself works fine.

These jars do not have source included in the, however there is a URL that can be used for Javadoc. I want to set this up programmatically for these classpath entries that the plug-in creates. This is what I'm doing:

  IClasspathEntry cpEntry;

  File[] jarFile = installFilePath.listFiles();

  IPath jarFilePath;
  for (int fileCount = 0; fileCount < jarFile.length; fileCount++)
  {
      jarFilePath = new Path(jarFile[fileCount].getAbsolutePath());
      cpEntry = JavaCore.newLibraryEntry(jarFilePath, null, null);
      entries.add(cpEntry);
  }

I could not figure out how to set the JavaDoc URL location on a claspath entry. This can be done in the Eclipse UI - for instance, if you right-click the project, go to Properties... -> Java Build Path, and expand one of the JAR entries and edit the "Javadoc Location", you can specify a URL. How do I do this from within a plug-in?

解决方案

I use the following:

        Path   pth = new Path( MY_JARFILE_LOCATION );
        Path   pthd = new Path( MY_JAVADOC_LOCATION );
        ClasspathAttribute att = new ClasspathAttribute("javadoc_location", "file:" + pthd.toOSString());
        IClasspathAttribute[] atts = new IClasspathAttribute[] { att };
        IClasspathEntry cpISDI = JavaCore.newLibraryEntry(pth, null, null, null, atts, false);
        cpEntries.add(1, cpISDI);
