Java项目IntelliJ配置命令行运行遇错：无法找到或加载主类.normalize

Looks like the issue here is that you're mixing up the terminal script (./normalize) with the actual Java main class IntelliJ needs to target. Let's break this down and get your run configuration working step by step:

1. Find your real main class #

The ./normalize command you use in the terminal is almost certainly a shell script (or executable wrapper) that runs a java command under the hood. You need to track down the full qualified name of the actual Java class with the public static void main(String[] args) method — this is your project's entry point:

• Search your project codebase for classes containing the main method. It’ll look something like com.yourteam.normalize.Normalize (adjust the package path to match your project structure).
• If you use Maven or Gradle:
  • For Maven, check plugins like maven-shade-plugin or spring-boot-maven-plugin — they usually explicitly define the main class in their configuration.
  • For Gradle, look for the application plugin’s mainClass property in your build file.

2. Configure IntelliJ's Run/Debug Configuration #

Once you have the main class name, set up your run config properly:

• Go to Run > Edit Configurations in the top menu bar.
• Click the + icon in the top-left corner and select Application from the dropdown.
• In the Main class field, paste the full qualified name of your main class (e.g., com.yourteam.normalize.Normalize — do NOT use ./normalize here, that’s the script name, not a valid class).
• In the Program arguments field, paste exactly the parameters you use in the terminal:

  --manifest /MyUsrPath/myFile.csv --input /MyUsrPath/myOtherFile.csv
  

• Ensure the Working directory matches the folder you’re in when running the script from the terminal (this is usually your project’s root folder).
• Click Apply then OK to save the config.

3. Extra fixes if it still fails #

• If ./normalize has custom classpath settings or VM arguments, open the script file and look for lines starting with java. Copy any -cp/-classpath values into IntelliJ’s Classpath section, or any VM flags into the VM options field of your run config.
• Run Build > Build Project to confirm all classes compile correctly — fix any compilation errors before trying to run again.
