无法为Scala 2.12编译Flink 1.7.2：Maven enforcer发现禁止的依赖项

Question

我正在尝试为Scala 2.12编译Flink 1.7.2，以获得AWS Kinesis连接器，该连接器被排除在二进制分发之外，如here所述。

我从here下载了源代码并使用了以下命令：

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

但是我收到以下错误：

[INFO] --- maven-enforcer-plugin:3.0.0-M1:enforce (enforce-versions) @ flink-runtime_2.12 ---
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.BannedDependencies failed with message:

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

我不明白为什么这些依赖被禁止，因为在pom.xml配置文件中的scala-2.12，依赖关系被禁止这样：

<!-- 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>

以前，我成功编译了Flink for Scala 2.11。为了确保我的环境没有从之前的编译中被污染，我删除并重新下载了Flink源代码，并且我完全删除了.m2 Maven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构建。并记得使用JDK8进行构建。
