@Jackie-Jiang > Change the eclipse format to follow the current intellij format as much as possible (e.g. new line for exception, new space for array declaration etc.). We should not see almost all files reformatted For "new line for exception", in Intellj, it's corresponding option is called "always wrap throws keyword":  Unfortunately, Eclipse formatter does not has such a option, here is a complete list of Eclipse formatter options: https://github.com/eclipse/eclipse.jdt.core/blob/7e35bbd8b9cc36a449e562c61841f9968ec4bec3/org.eclipse.jdt.core/formatter/org/eclipse/jdt/internal/formatter/DefaultCodeFormatterOptions.java#L122-L524 For `new space for array declaration etc`, I have change the codestyle-eclipse.xml file to match IntellJ behavior. So, it's almost impossible to make the maven plugin be consistent with IntellJ behavior if we use eclipse formatter given that IntellJ/Eclipse provide different options. If we wanner keep consistency across IntellJ IDE, Eclipse IDE and maven plugin, the only choice is [the google formatter](https://github.com/google/google-java-format), which has plugin for both IntellJ/Eclipse/Maven. The drawback is: * the tool enforces [Google Java style guide](https://google.github.io/styleguide/javaguide.html), which was [praised and recommended by the Oracle Java team as described in the Oracle Java magazine](https://alanzeichick.com/2016/11/wheres-best-java-coding-style-guide-not-oracle.html) though, the tool itself does not allow too much config by design. Copied form google-java-format project home page: ``` Note: There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. ``` * The tool will mess up license header, see: https://github.com/diffplug/spotless/issues/843. If there is no solution/workaround, it's impossible to be used for pinot. -- This is an automated message from the Apache Git Service.
