Question

我希望在执行string = input('Enter a string:') #space for most popular character pop_char = '' #initialize number of times character appears num = 0 #initialize index index = 0 # pick one character at a time for ch in string: #initialize character counter cc=0 #go through entire string and compare the character to the string characters while index < len(string): #if they are the same (converted to lower case), tally one to cc if ch.lower() == string[index].lower(): cc = cc + 1 index = index + 1 #if count is greater than or equal to previous count, use this for #popular character if cc >= num: num = cc pop_char = ch else: index = index + 1 print('The most frequently occuring letter(s):', pop_char)目标时排除父pom（以下代码所在的位置），我无法找到示例或自行解决：

package:copy

无论<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.10</version> <executions> <execution> <id>copy</id> <phase>package</phase> <goals> <goal>copy</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>${project.groupId}</groupId> <artifactId>${project.artifactId}</artifactId> <version>${project.version}</version> <type>${project.packaging}</type> <classifier>shaded</classifier> <destFileName>${project.name}.${project.packaging}</destFileName> <excludes>*.pom</excludes>  </artifactItem> </artifactItems> <outputDirectory>${rootdir}/target/modules</outputDirectory> <silent>true</silent> <overWriteReleases>true</overWriteReleases> <overWriteSnapshots>true</overWriteSnapshots> </configuration> </execution> </executions> </plugin>内的<excludes>设置如何，它仍然包含我的父项目artifactItem。我想将文件排除在复制到NiftyParent.pom目录之外。

如果有人问，${rootdir}/target/modules属性只指向父项目目录而没有硬编码相对/绝对路径（为了参数的原因${rootdir}。

您可以使用plugin的skip配置元素以及父级及其模块中定义的Maven property来跳过执行。

在您的父pom中，您可以将其配置如下：

<properties>
    <skip-dependency-copy>true</skip-dependency-copy>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.10</version>
            <executions>
                <execution>
                    <id>copy</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy</goal>
                    </goals>
                    <configuration>
                        <artifactItems>
                            <artifactItem>
                                <groupId>${project.groupId}</groupId>
                                <artifactId>${project.artifactId}</artifactId>
                                <version>${project.version}</version>
                                <type>${project.packaging}</type>
                                <classifier>shaded</classifier>
                                <destFileName>${project.name}.${project.packaging}</destFileName>
                            </artifactItem>
                        </artifactItems>
                        <outputDirectory>${rootdir}/target/modules</outputDirectory>
                        <silent>false</silent>
                        <overWriteReleases>true</overWriteReleases>
                        <overWriteSnapshots>true</overWriteSnapshots>
                        <skip>${skip-dependency-copy}</skip>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

请注意附加属性和skip元素配置。

然后，在每个模块中，您只需配置以下内容：

<properties>
    <skip-dependency-copy>false</skip-dependency-copy>
</properties>

因此，我们实际上是根据父/模块位置打开/关闭它。这种方法的另一个优点是你也可以跳过一些模块（如果需要），并能够从命令行（覆盖已定义的属性值）通过for为所有（在你的情况下关闭）打开/关闭它实例：

mvn package -Dskip-dependency-copy=true

此方法不使用插件配置，但在许多其他插件和案例中需要跳过时，它通常会被使用。

复制子模块时不要复制父pom
