只要在执行gradle init的目录中存在pom.xml文件，就可以基于此文件转换为build.gradle和settings.xml。但是正如日志中提到的“Maven to Gradle conversion is an incubating feature.”，相信这个功能信任度较低，使用时应小心谨慎。

环境

Gradle版本为8.3。

源代码等

使用Spring Initializr创建一个基本的pom.xml文件。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>

		<relativePath/> <!-- lookup parent from repository -->

	</dependencies>

		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

运行gradle init命令。运行时的日志如下所示。

>gradle init
Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details

使用与Gradle无关的Spring Boot插件确实不会被自动转换。虽然在转换之后需要手动修正，但如果将其作为从Maven迁移到Gradle的起点，它可能是有用的。
