我正在尝试为 Scala 2.12 编译 Flink 1.7.2，以获取 AWS Kinesis 连接器，它被排除在二进制发行版之外，如此处所述。

我从这里下载了源代码并使用了以下命令：

mvn clean install -Pscala-2.12 -Pinclude-kinesis -DskipTests

但我收到以下错误：

[INFO] --- maven-enforcer-plugin:3.0.0-M1:enforce (enforce-versions) @ flink-runtime_2.12 ---

Use 'mvn dependency:tree' to locate the source of the banned dependencies.

我不明白为什么要禁止这些依赖项，因为pom.xml在scala-2.12配置文件中，这些依赖项以这种方式被禁止：

<!-- make sure we don't have any _2.10 or _2.11 dependencies when building
for Scala 2.12 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-enforcer-plugin</artifactId>
    <executions>
        <execution>
            <id>enforce-versions</id>
            <goals>
                <goal>enforce</goal>
            </goals>
            <configuration>
                <rules>
                    <bannedDependencies>
                        <excludes combine.children="append">
                            <exclude>*:*_2.11</exclude>
                            <exclude>*:*_2.10</exclude>
                        </excludes>
                    </bannedDependencies>
                </rules>
            </configuration>
        </execution>
    </executions>
</plugin>

之前，我成功为 Scala 2.11 编译了 Flink。为了确保我的环境没有被之前的编译污染，我删除并重新下载了 Flink 源，并彻底清除了.m2Maven 缓存。

这是仅在 1.9.0 中修复的 flink 错误，有关详细信息，请参阅https://issues.apache.org/jira/browse/FLINK-12007。

作为一种解决方法，使用mvn clean install -Pinclude-kinesis -DskipTests -Pscala-2.12 -Dscala-2.12. 并记住使用 JDK8 进行构建。
