You need to install the google-java-format plugin. Spotless together with google-java-format is used to format the codes.

It is recommended to automatically format your code by applying the following settings:

1. Go to "Settings" → "Other Settings" → "google-java-format Settings".
2. Tick the checkbox to enable the plugin.
3. Change the code style to "Android Open Source Project (AOSP) style".
4. Go to "Settings" → "Tools" → "Actions on Save".
5. Under "Formatting Actions", select "Optimize imports" and "Reformat file".
6. From the "All file types list" next to "Reformat code", select "Java".

For earlier IntelliJ IDEA versions, the step 4 to 7 will be changed as follows.

• 4.Go to "Settings" → "Other Settings" → "Save Actions".
• 5.Under "General", enable your preferred settings for when to format the code, e.g. "Activate save actions on save".
• 6.Under "Formatting Actions", select "Optimize imports" and "Reformat file".
• 7.Under "File Path Inclusions", add an entry for .*\.java to avoid formatting other file types. Then the whole project could be formatted by command mvn spotless:apply.

Checkstyle is used to enforce static coding guidelines.

1. Go to "Settings" → "Tools" → "Checkstyle".
2. Set "Scan Scope" to "Only Java sources (including tests)".
3. For "Checkstyle Version" select "8.14".
4. Under "Configuration File" click the "+" icon to add a new configuration.
5. Set "Description" to "doris-flink-connector".
6. Select "Use a local Checkstyle file" and link it to the file tools/maven/checkstyle.xml which is located within your cloned repository.
7. Select "Store relative to project location" and click "Next".
8. Configure the property checkstyle.suppressions.file with the value suppressions.xml and click "Next".
9. Click "Finish".
10. Select "doris-flink-connector" as the only active configuration file and click "Apply".

You can now import the Checkstyle configuration for the Java code formatter.

1. Go to "Settings" → "Editor" → "Code Style" → "Java".
2. Click the gear icon next to "Scheme" and select "Import Scheme" → "Checkstyle Configuration".
3. Navigate to and select tools/maven/checkstyle.xml located within your cloned repository.

Then you could click "View" → "Tool Windows" → "Checkstyle" and find the "Check Module" button in the opened tool window to validate checkstyle. Or you can use the command mvn clean compile checkstyle:checkstyle to validate.
