关于Eclipse未检测到删除令牌及代码错误的解决方法咨询

Hey there, let's tackle these two Eclipse issues you're facing one by one—they're pretty common, so I've got some tried-and-true fixes to share:

Here are some actionable steps to resolve this:

• Refresh your project & clean the workspace：Eclipse's cache often causes detection lags. Right-click your project and select Refresh, then go to Project > Clean, choose your project or the entire workspace, and restart Eclipse. This fixes most minor detection issues.
• Verify token storage location & Eclipse's scan scope：If the token is stored in an external file or system environment variable, make sure Eclipse can access it. For environment variables, check Run > Run Configurations > Environment to see if the variable is loaded. For external files, add them to your project's build path via Build Path > Add External Archives or Link Source.
• Check plugin/tool configurations for tokens：If you're using a specific plugin (like OAuth tools) to manage tokens, head to the plugin's settings page to ensure real-time detection is enabled. Some plugins require manual refreshes or have an auto-refresh toggle that might be off.
• Review Eclipse's error log：Open Window > Show View > Other > General > Error Log to look for related errors—like permission issues or file read exceptions. These logs can pinpoint the root cause quickly.

Try these fixes to get error detection back on track:

• Ensure automatic build is enabled：First, check if Project > Build Automatically is checked. If not, Eclipse won't scan for errors in real-time—you'll have to manually run Project > Build Project every time.
• Check JDK/JRE configuration consistency：Mismatched JDK versions are a common culprit. Right-click your project, go to Properties > Java Build Path > Libraries to verify the JRE System Library matches your project's JDK version. Then confirm the compiler version in Properties > Java Compiler aligns with it.
• Reset Eclipse's code analyzer settings：Corrupted analyzer configurations can break error detection. Go to Window > Preferences > Java > Compiler > Errors/Warnings, click Restore Defaults to reset to default rules, then restart Eclipse. You can reconfigure custom rules later if needed.
• Clean & rebuild the project index：Damaged index files often cause detection failures. Close your project, find the hidden .metadata folder in your workspace directory, delete the .indexes and .markers subfolders, then reopen the project. Eclipse will rebuild the index from scratch.
• Rule out plugin conflicts：If this started after installing a new plugin, launch Eclipse in safe mode with the command eclipse.exe -clean -safe. If error detection works here, disable recently installed plugins one by one to find the conflicting one.
