Maven 项目构建到 jar 和 war

Question

我有一个包含以下 pom.xml 的项目，我已经从中删除了一些不需要的东西。我打算发生的是生成一个 jar 文件并最终生成一个 war 包，其中包含 jar 文件作为库。不幸的是，以下 pom.xml.

似乎没有发生这种情况

<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>test</artifactId>
    <groupId>com.test.abcd</groupId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>
    <name>Test Application</name>

    ....

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>${maven-compiler-plugin.version}</version>
            <configuration>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>${mapstruct.version}</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <warSourceDirectory>target/www/</warSourceDirectory>
            </configuration>
            <executions>
                <execution>
                    <id>build-war-in-classes</id>
                    <phase>package</phase>
                    <goals>
                        <goal>war</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>

</project>

尽管这会在打包阶段同时生成 jar 和 war，但 war 不包含 jar 文件（WEB-INF/lib/test-0.0.1-SNAPSHOT.jar ) 作为一个库，相反我看到以下类,

META-INF/
META-INF/MANIFEST.MF
....
WEB-INF/
WEB-INF/classes/
....

什么可能导致此行为？

我认为您在 war 插件配置中缺少一个 conf 标志：

        <configuration>
          <archiveClasses>true</archiveClasses>
        </configuration>

How do I create a JAR containing the classes in my webapp?

If you would simply like to package the classes and resources as a JAR in WEB-INF/lib rather than as loose files under WEB-INF/classes, use the following configuration:
          <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.1.0</version>
            <configuration>
              <archiveClasses>true</archiveClasses>
            </configuration>
          </plugin>
