リソースの取得方法

Eclipseの実行ファイル　eclipse.exe の場所

java.io.File f = new File("eclipse.exe");
String path = f.getAbsolutePath()

ワークスペースの場所

ResourcesPlugin.getWorkspace().getRoot().getLocation().toOSString()

プラグイン内のリソース

try {
 Bundle bundle = Platform.getBundle("com.xxx");//プラグインID
 URL bundleUrl = bundle.getResource("icons");//プラグインからのリソースパス
 URL fileUrl = org.eclipse.core.runtime.FileLocator.toFileURL(bundleUrl);//変換
 bundlePath = fileUrl.toString();

 //getPath()でも可
 pluginEntryPath = fileUrl.getPath();
 // なぜか先頭は'/'となる
 // path = /C:/・・・eclipse/workspace/com.xxx/
 if (pluginEntryPath.charAt(0) == '/') {
   pluginEntryPath = pluginEntryPath.substring(1);
 }

} catch (IOException e) {
}
