如何在项目中正确执行 "mvn clean"？

Question

我正在尝试清理、构建和打包我的项目，但我不断收到此错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:2.6.1:clean (auto-clean) on project Presentation: Unable to parse configuration of mojo org.apache.maven.plugins:maven-clean-plugin:2.6.1:clean for parameter retryOnError: Cannot find 'retryOnError' in class org.apache.maven.plugin.clean.CleanMojo -> [Help 1]

一段时间以来，我一直在尝试自己解决这个问题。我将项目设置为自动清理，这正是 Apache 在 pom 文件中指示这样做的方式，但我也会将其包括在内。

<project>
    <build>
        ...
        <plugin>
            <artifactId>maven-clean-plugin</artifactId>
            <version>2.6.1</version>
            <configuration>
                <failOnError>false</failOnError>
            </configuration>
            <executions>
                <execution>
                    <id>auto-clean</id>
                    <phase>initialize</phase>
                    <goals>
                        <goal>clean</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        ...
    </build>
<project>

我在这里迷路了。很明显，它与'retryOnError'有关，但这不是我自己添加的。我在哪里可以找到它？

此外，如果有帮助，我正在使用 Maven 3.2.5。

Answer 1

@ɐuıɥɔɐɯ说的对。

我也会尝试删除您的 pom.xml 中的自动清理插件配置，因为找出它导致问题的原因可能比它值得做的更多。现在，我只需运行在项目的根文件夹中执行以下命令：

mvn clean package

那应该运行你的目标在你的 pom.xml 中列出，并清理你的 "target" 子目录，用最新的代码替换它。

有关详细信息，请参阅 http://www.mkyong.com/maven/how-to-clean-project-with-maven/。

Answer 2

看起来您明确配置的 clean 插件版本与 maven 附带的版本不同（或默认属性中的类似不匹配）

正如上面的评论所建议的那样，我将删除 :

的整个部分

<plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <version>2.6.1</version>
    <configuration>
        <failOnError>false</failOnError>
    </configuration>
    <executions>
        <execution>
            <id>auto-clean</id>
            <phase>initialize</phase>
            <goals>
                <goal>clean</goal>
            </goals>
        </execution>
    </executions>
</plugin>

然后运行一个 mvn clean / mvn clean 包。

如果您打算使用插件，您还应该尝试在配置中手动设置属性，如下所示：

<plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <version>2.6.1</version>
    <configuration>
        <failOnError>false</failOnError>
        <retryOnError>true</retryOnError>
    </configuration>
    <executions>
        <execution>
            <id>auto-clean</id>
            <phase>initialize</phase>
            <goals>
                <goal>clean</goal>
            </goals>
        </execution>
    </executions>
</plugin>
