Maven中的pluginManagement范围和reporting.plugins.plugin.version缺少警告

Question

我的Maven项目给了我report.plugins.plugin.version这样的警告:

[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Maven 3 对插件版本更严格,必须指定插件版本.我在pluginManagement中指定了该版本:

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

当我使用插件时,这工作正常,没有警告build/plugins:

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

但是,它不起作用reporting/plugins:

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

我的问题是:指定的版本范围是否build/plugingManagement仅限于<build>标签内？我可以修复警告而不在两个地方复制插件版本吗？

以下是生成警告的完整示例:

            </plugins>
        </pluginManagement>
    </build>

Answer 1

这似乎是较旧的maven版本中的一个错误.看看apache 上的这个bug票.

.尝试使用Maven 3和maven-site-plugin-3.
