我有一个用于 Spring Boot 项目的 Maven POM。POM 导入 Spring Boot BOM。现在我想自定义一个 Maven 插件的配置,比如mvn-compiler-plugin. 我想使用BOMmaven-compiler-plugin.version规定的插件版本。spring-boot-dependencies

<?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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>ch.ge.mygroup</groupId>
    <artifactId>myartifact</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <properties>
        <spring-boot.version>2.4.2</spring-boot.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <!-- Spring Boot BOM -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven-compiler-plugin.version}</version>
                <configuration>
                    <!-- some particular config here -->
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

但这确实有效:我想出了一个 Maven 错误:

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin must be a valid version but is '${maven-compiler-plugin.version}'. @ line 31, column 26

所以我必须明确指定我想要避免的 Maven 插件的版本。

总之:

使用

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>${maven-compiler-plugin.version}</version>
  <configuration>
    <!-- some particular config here -->
  </configuration>
</plugin>

产生一个 Maven 错误。

使用

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
  <configuration>
    <!-- some particular config here -->
  </configuration>
</plugin>

有效,但阻止我使用 Spring Boot BOM 规定的版本(3.8.1)。

使用

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <!-- some particular config here -->
  </configuration>
</plugin>

工作,但使用插件的旧版本(3.1)。

如何避免显式指定插件版本,而是隐式使用 Spring Boot BOM 中提供的插件版本?

如果您想通过简单地更新属性来覆盖 Spring Boot 依赖项,则必须指定父 POM 而不是importing:

<?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">
  <modelVersion>4.0.0</modelVersion>

  <groupId>ch.ge.mygroup</groupId>
  <artifactId>myartifact</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>war</packaging>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.4.2</version>
    <relativePath/>
  </parent>

  <properties>
    <spring-boot.version>2.4.2</spring-boot.version>
    <maven-compiler-plugin.version>3.7.0</maven-compiler-plugin.version>
  </properties>

  <build>
    <plugins>
      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${maven-compiler-plugin.version}</version>
        <configuration>
          <!-- some particular config here -->
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>
