Eclipse(Kepler)无法安装Properties Editor插件求助

Hey there, let's break down your issue and work through practical fixes. You've got two versions of the Propedit plugin (jp.gr.java_conf.ussiy.app.propedit_5.3.3.zip and 6.0.5), and both failed to install using two common methods:

• Extracting the zip directly to Eclipse's dropins directory
• Copying contents from the extracted features and plugins folders to Eclipse's corresponding directories
  For the 6.0.5 version, you tried both copying the feature JARs as-is and extracting them first—still no luck. Your environment runs JDK 1.6.0_45 (64-bit).

Here are targeted steps to resolve this:

1. Verify Plugin-Eclipse-JDK Compatibility First #

The most likely culprit here is version mismatch. Propedit 6.0.5 almost certainly requires a newer Java version (like Java 8+) but you're on JDK 1.6, which is extremely outdated. JDK 1.6 typically pairs with older Eclipse versions (e.g., Eclipse 3.x or early 4.x), which won't support the 6.0.5 plugin at all.

• First, check your Eclipse version: Go to Help > About Eclipse to get the exact version number.
• Stick with the 5.3.3 version first—it's far more likely compatible with JDK 1.6 and your older Eclipse. Save 6.0.5 for if you end up upgrading your JDK/Eclipse later.

2. Fix the dropins Directory Structure #

Most dropins failures happen because the folder structure is wrong. Try this correct approach:

• Extract the 5.3.3 zip to get a folder named something like jp.gr.java_conf.ussiy.app.propedit_5.3.3. Move this entire folder directly into Eclipse's dropins directory (don't dump the inner features/plugins here).
• Alternatively, create a propedit subfolder inside dropins, then make features and plugins subfolders under that. Copy the 5.3.3 features contents to dropins/propedit/features and plugins contents to dropins/propedit/plugins.
• Critical step: Fully shut down Eclipse, delete the configuration/org.eclipse.update folder in your Eclipse installation directory, then restart Eclipse. This forces Eclipse to rescan all plugins from scratch.

3. Use Eclipse's Official Offline Installation Wizard (Most Reliable) #

This method avoids manual folder copying errors:

1. Close Eclipse completely.
2. Extract your Propedit zip to a temporary folder (you'll see features and plugins inside).
3. Open Eclipse, go to Help > Install New Software.
4. Click the Add button, then Local in the popup window. Select the temporary folder you extracted the plugin to, name the repository something like Propedit Local, and click OK.
5. The Propedit plugin should appear in the list—check the box next to it, follow the installation wizard prompts, and restart Eclipse when prompted.

4. Check Eclipse Logs for Exact Errors #

If none of the above works, the Eclipse log will tell you exactly what's failing:

• Find the log at <your-workspace>/.metadata/.log
• Search for entries containing propedit or jp.gr.java_conf.ussiy—you'll see errors like missing classes, version conflicts, or permission issues that point to the root cause.

One final note: JDK 1.6 is way past its end-of-life. If you can, upgrade to JDK 8 (which is still widely supported) and a compatible Eclipse version—this will make installing modern plugins like Propedit 6.0.5 much smoother.
