java - Vaadin 8 与 Vaadin 7 兼容包：Sass 编译器失败

Question

我正在做一个使用 Vaadin7 的项目。我使用 pom.xml 中的兼容性将项目从 vaadin 7 转换为 vaadin 8 。我解决了此 vaadin 迁移所需的所有依赖项，但是当我构建项目时，它会抛出 com.vaadin.sass.SassCompiler 错误。

以前的 pom 环境：-

    <dependency>
                <groupId>com.vaadin</groupId>
                <artifactId>vaadin-themes</artifactId>
                <version>7.5.10</version>
            </dependency>
            <dependency>
                <groupId>com.vaadin</groupId>
                <artifactId>vaadin-client-compiled</artifactId>
                <version>7.5.10</version>
            </dependency>
            <dependency>
                <groupId>com.vaadin</groupId>
                <artifactId>vaadin-client</artifactId>
                <version>7.5.10</version>
                <exclusions>
                    <exclusion>
                        <groupId>javax.validation</groupId>
                        <artifactId>validation-api</artifactId>
                    </exclusion>
                </exclusions>
     </dependency>

当前 pom 环境：-

插件环境：-

                </executions>
</plugin>

当我尝试使用mvn install命令构建项目时，它给了我以下错误：-
