+
+Coding convention is very important for teamwork. Not only it keeps code neat
and tidy, it saves a lot of work too. Different coding convention (and auto
formatter) will cause unnecessary code changes that requires more effort at
code review and code merge.
+
+## Setup IDE code formatter
+
+For Java code, we use Eclipse default formatter setting, with one change that
to allow long lines.
+
+- For Eclipse developers, no manual setting is required. Code formatter
configurations `src/core-common/.settings/org.eclipse.jdt.core.prefs` is on git
repo. Your IDE should be auto configured when the projects are imported.
+
+- For intellij IDEA developers, you need to install `Eclipse Code Formatter`
and load the Eclipse formatter settings into your IDE manually.
+
+ you have to do a few more steps:
+
+ 1. Install `Eclipse Code Formatter` and use `org.eclipse.jdt.core.prefs` and
`org.eclipse.jdt.ui.prefs` in `src/core-common/.settings` to configure `Eclipse
Java Formatter config file` and `Import order`.
+
+ 
+
+ 2. Go to Preference => Code Style => Java, set `Scheme` to Default, and set
both Class count to use import with `*` and Names count to use static import
with `*` to 99.
+
+ 
+
+ 3. Disable intellij IDEA’s `Optimize imports on the fly`
+
+ 
+
+ 4. Format the code before committing the code.
+
+## Setup IDE license header template
+
+Each source file should include the following Apache License header
+
+```shell
+Licensed to the Apache Software Foundation (ASF) under one
+or more contributor license agreements. See the NOTICE file
+distributed with this work for additional information
+regarding copyright ownership. The ASF licenses this file
+to you under the Apache License, Version 2.0 (the
+"License"); you may not use this file except in compliance
+with the License. You may obtain a copy of the License at

+WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
+See the License for the specific language governing permissions and
+limitations under the License.
+```
+
+The checkstyle plugin will check the header rule when packaging also. The
license file locates under `dev-support/checkstyle-apache-header.txt`. To make
it easy for developers, please add the header as Copyright Profile and set it
as default for Kylin project.
+
+
+
+## Code Rules(Important)
+
+1. For JavaScript, XML, and other code, please use space for indent. And as a
general rule, keep your code format consistent with existing lines. No other
enforcement at the moment.
+
+2. Using `StringUtils`, just use the `StringUtils` of
`org.apache.commons.lang3.StringUtils` and
`io.kyligence.kap.guava20.shaded.common.base.Strings`.
+
+3. Using the `guava` in the package of `io.kyligence.kap.guava20.shaded.`.
+
+4. Don't use `log4j` directly, please use `slf4j`. Lombok uses the annotation
of `@Slf4j` and Factory class `org.slf4j.LoggerFactory`.
+
+5. Add a new test or modified a test.
+
+ 1) Please using the `junit5` instead of `junit4`. Example, Using the
annotation of `org.junit.jupiter.api.Test` instead of `org.junit.Test`.
+
+ 2) A test case which extends from `NLocalFileMetadataTestCase` need to
change with annotation `@MetadataInfo` and remove the `extend`.
+
+ > Example: org.apache.kylin.junit.MetadataExtension,
org.apache.kylin.metadata.epoch.EpochManagerTest
