Maven 中 pluginManagement 的范围 & reporting.plugins.plugin.version 缺少警告

Question

我的 Maven 项目给我 reporting.plugins.plugin.version 如下警告：

[WARNING] Some problems were encountered while building the effective model for com.example:test:jar:1.0-SNAPSHOT
[WARNING] 'reporting.plugins.plugin.version' for org.jacoco:jacoco-maven-plugin is missing. @ line 10, column 21

我知道必须指定 Maven 3 is stricter about plugin versions 和插件版本。我在pluginManagement中指定了版本：

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.7.2.201409121644</version>
        </plugin>
    </plugins>
</pluginManagement>

当我在 build/plugins:

中使用插件时，这工作正常并且没有警告

<build>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

它不起作用，然而，在reporting/plugins:

<reporting>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
        </plugin>
    </plugins>
</reporting>

我的问题是：build/plugingManagement中指定的版本范围是否仅限于<build>标签内？我可以在不在两个地方复制插件版本的情况下修复警告吗？

这是生成警告的完整示例：

            </plugin>
        </plugins>

        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.jacoco</groupId>

                    <version>0.7.2.201409121644</version>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

这似乎是旧版 Maven 中的错误。在 apache 上查看 this bug ticket。

。尝试使用 Maven 3 和 maven-site-plugin-3。
