java - Maven:找不到符号

Question

我正在尝试运行 Java 项目的 Maven 构建，但测试失败，表明尽管已导入，但无法创建播放器符号。

Maven 构建失败如下:

在您的 Maven-compiler-plugin 定义中:

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <includes>
                    <include>src</include>
                </includes>
            </configuration>
        </plugin>

不要直接包含 src 文件夹。 这会打乱编译顺序，Maven 最终首先构建测试文件夹，然后由于缺少主要类而失败。将其更改为此以使其工作:

        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
        </plugin>
