1. Install graalvm
tar -xzf graalvm-ce-java-linux–.tar.gz
export PATH=/path/to//bin:$PATH
export JAVA_HOME=/path/to/
2. Install native-image
https://docs.oracle.com/en/graalvm/enterprise/21/docs/reference-manual/native-image/BuildConfiguration/
https://gitee.com/westinyang/java-graalvm-start
gu install native-image
3. Precautions for using native-image
The memory of the machine should be slightly larger, otherwise this error will be reported: exit status 137
4. Use native-image to directly compile the jar of spring boot/spring cloud/spring cloud alibaba as an independent executable file. If it fails, give up:
Case 1: native-image does not add –no-fallback, the compiled executable file, at runtime, also depends on java and the original jar
Situation 2: But the executable file compiled with native-image –no-fallback -jar xxx.jar runs and reports this error: zip END header not found
So, please refer to the following to achieve:
5. Compile spring boot/spring cloud/spring cloud alibaba with maven
(4.1) Situation 1: Project inheritance spring-boot-starter-parent
In the pom.xml of the submodule, add the following content:
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
<configuration>
<!--Executable file that runs independently -->
<buildArgs>
<arg>--no-fallback</arg>
<!-- org.apache.poi: Caused by: java.nio.charset.UnsupportedCharsetException: CP1252 -->
<!--<arg>-H: + AddAllCharsets</arg>-->
</buildArgs>
<executions>
<execution>
<id>add-reachability-metadata</id>
<goals>
<goal>add-reachability-metadata</goal>
<!--Triggered when compiling, specially added -->
<goal>compile</goal>
</goals>
</execution>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>
-agentlib:native-image-agent=config-merge-dir=src/main/resources/META-INF/native-image/
</jvmArguments>
</configuration>
</plugin>
Operation mode one:
Because profile native is defined in spring-boot-starter-parent, you can use:
(1) Execute mvn package in the project root directory
(2) Then cd to the submodule and execute: mvn -Pnative native:compile
(4.2) Situation 2: The project does not inherit spring-boot-starter-parent, but uses spring-boot-dependencies
<dependencyManagement>
<dependencies>
<!-- Spring Boot -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencyManagement>
Reference: spring-boot-starter-parent, copy the relevant content, and delete some dependencies that are not used by your own project.

<artifactId>native-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>

</plugin>
</plugins>
run:
(1) If you do not want to generate a native image, execute:
mvn package
(2) If you want to generate a native image, execute:
mvn package -P prod
The advantage of this is: there is no need to enter a module separately to execute mvn -P native native:compile
