+## Building the Project Locally
+Amoro is built using Maven with Java 1.8 and Java 17(only for `mixed/trino` module).
+
+* To build Trino module need config `toolchains.xml` in `${user.home}/.m2/` dir, the content is
+
+```
+<?xml version="1.0" encoding="UTF-8"?>
+<toolchains>
+    <toolchain>
+        <type>jdk</type>
+        <provides>
+            <version>17</version>
+            <vendor>sun</vendor>
+        </provides>
+        <configuration>
+            <jdkHome>${YourJDK17Home}</jdkHome>
+        </configuration>
+    </toolchain>
+</toolchains>
+```
+
+* To invoke a build and run tests: `mvn package -P toolchain`
+* To skip tests: `mvn -DskipTests package -P toolchain`
+* To package without trino module and JAVA 17 dependency: `mvn clean package -DskipTests -pl '!mixed/trino'`
+* To build with hadoop 2.x(the default is 3.x) `mvn clean package -DskipTests -Dhadoop=v2`
+* To indicate Flink version for optimizer (the default is 1.18.1): `mvn clean package -Dflink-optimizer.flink-version=1.15.4`. If the version of Flink is below 1.15.0, you also need to add the `-Pflink-pre-1.15` parameter: `mvn clean package -Pflink-pre-1.15 -Dflink-optimizer.flink-version=1.14.6`.
+  `mvn clean package -Pflink-pre-1.15 -Dflink-optimizer.flink-version=1.14.6 -DskipTests`
+
+>Spotless is skipped by default in `trino` module. So if you want to perform checkstyle when building `trino` module, you must be in a Java 17 environment.
+
+* To invoke a build include `mixed/trino` module in Java 17 environment: `mvn clean package -DskipTests -P trino-spotless`
+* To only build `mixed/trino` and its dependent modules in Java 17 environment: `mvn clean package -DskipTests -P trino-spotless -pl 'mixed/trino' -am`
