我正在尝试遵循hello-samza基本设置，无法通过"构建Samza工作包"。当我运行的是最新的，我尝试运行gradle指定:
$ ./gradlew publishToMavenLocal
FAILURE: Build failed with an exception.
* What went wrong:
Task 'publishToMavenLocal' not found in root project 'hello-samza'.
* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
然后我看到引导程序实际上运行了它所以我想我可以进入下一步:
$ mvn clean package
经过一系列输出后，最终失败:

然后用-X开关运行它，看到一堆这样的错误:
org.eclipse.aether.transfer.MetadataTransferException: Could not transfer metadata org.apache.samza:samza-kafka_2.10:0.11.0-SNAPSHOT/maven-metadata.xml from/to scala-tools.org (https://oss.sonatype.org/content/groups/scala-tools): Access denied to: https://oss.sonatype.org/content/groups/scala-tools/org/apache/samza/samza-kafka_2.10/0.11.0-SNAPSHOT/maven-metadata.xml , ReasonPhrase:Forbidden.
我不知道如何从这里开始。我知道我已经设法让以前的版本为我工作。这可能与linux(我以前的环境)和OS X(我现在的环境)之间的差异有关吗?
谢谢-使用0.10.1也为我工作(在Mac 15.6上)。为了明确起见，我在构建目录(.../hello-samza)中更改了pom.xml，如下所示:
146c146
< <samza.version>0.11.0-SNAPSHOT</samza.version>
---
> <samza.version>0.10.1</samza.version>
所以，感谢dev@samza.apache.org上一个非常有帮助的用户，他引导我更仔细地观察了pom。我意识到分支"最新"指向的是samza 0.11版本，而我显然没有访问权限。
然后我检查了master中的pom，它指向当前的稳定版本10.1。通过回到主分支，我能够编译并继续。
