【问题描述】：

我想在Intellij idea IDE 中从我的代码生成javadoc。
我将一步一步地通过This link。但我没有得到合适的结果。

但是在执行mvn package 之后，目标文件夹下既没有attach-source-javadoc-1.0-SNAPSHOT-javadoc.jar 也没有attach-source-javadoc-1.0-SNAPSHOT-sources.jar 文件。

这是整个 pom 文件：

  <?xml version="1.0" encoding="UTF-8"?>

【问题讨论】：

除了@Jens 的回答，我在这里添加 URL 作为参考 Generate javadoc jar for maven based project Generate source code jar for maven based project 同样在每个插件中，您可以定义一个 <version> 属性。

标签： maven intellij-idea javadoc maven-javadoc-plugin

【解决方案1】：

您已将插件添加到未执行的<pluginManagement>。

通过 maven-plugins 生成 javadoc 和 source code
你必须把这个直接放在<plugins>里面：

<build>
    <plugins>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-source-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-sources</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-javadocs</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <failOnError>false</failOnError>
            </configuration>
        </plugin>

    </plugins>
</build>
