出于某种原因,当我执行 mvn install 并检查我的本地 repo 并查看那里的 pom 时,我没有看到 version 变量被替换为值。

我在属性中使用带有版本的pom

<properties>
    <maven.javadoc.skip>true</maven.javadoc.skip>
    <revision>19.3.29</revision>
</properties>

它还包含 flatten 插件条目:

          <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>flatten-maven-plugin</artifactId>
                <version>1.2.2</version> 
                <configuration>
                    <updatePomFile>true</updatePomFile>
                    <flattenMode>resolveCiFriendliesOnly</flattenMode>
                </configuration>
                <executions>
                    <execution>
                        <id>flatten</id>
                        <phase>process-resources</phase>
                        <goals>
                            <goal>flatten</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>flatten.clean</id>
                        <phase>clean</phase>
                        <goals>
                            <goal>clean</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

pom使用${revision} 作为版本和 ${project.version} 的值作为maven推荐的依赖项:

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <artifactId>analysisModule</artifactId>
    <version>${revision}</version>
    <parent>
        <groupId>com.mycompany.analysis</groupId>
        <version>1.0.0</version>
        <artifactId>autoav</artifactId>
        <relativePath>../autoAV</relativePath>
    </parent>
    <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>
    <dependencies>
      <dependency>
        <groupId>com.mycompany.analysis</groupId>
        <artifactId>analysisCore</artifactId>
        <version>${project.version}</version>
      </dependency>
    </dependencies>
</project>

在我“mvn install”之后查看本地 repo pom xml:

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <artifactId>analysisJdbc</artifactId>
        <version>${revision}</version>
        <description>analysis of jdbc sources</description>
        <parent>
                <groupId>com.mycompany.analysis</groupId>
                <version>1.0.0</version>
                <artifactId>autoav</artifactId>
                <relativePath>../autoAV</relativePath>
        </parent>
        <build>
                <resources>
                        <resource>
                                <directory>src/main/resources</directory>
                                <filtering>true</filtering>
                        </resource>
                </resources>
        </build>
        <dependencies>
                <dependency>
                        <groupId>com.mycompany.analysis</groupId>
                        <artifactId>analysisCore</artifactId>
                        <version>${project.version}</version>
                </dependency>
...
</project>

${revision} & ${project.version}不应该用实际数字代替吗?这不是使用 flatten 插件的全部内容吗?

我跟着这个 https://www.mojohaus.org/flatten-maven-plugin/examples/example-central-version.html

添加我的 mvn install 输出(跳过测试)(maven 版本 3.3.9):

您需要将插件从 移动<pluginManagement><plugins><plugins>. 或者,您可以将其保留在那里,只需向该<plugins>部分添加一个简短的插件定义(包括 groupId 和 artifactId)。

<pluginManagement>只是为了预配置版本号和配置。插件在<pluginManagement>构建期间不会运行,除非它们重新出现在<plugins>.

我已经能够通过为依赖项创建另一个属性来实现这一点。此属性将与生成的 pom 文件具有相同的值${revision}并将被替换。

<properties>
    <revision>19.3.29</revision>
    <my-lib.version>${revision}</my-lib.version>
</properties>

然后,不要${project.version}在依赖项中使用,而是使用您的属性:

<dependency>
    <groupId>com.mycompany.analysis</groupId>
    <artifactId>analysisCore</artifactId>
    <version>${my-lib.version}</version>
</dependency>
