使用Datadog投掷java.lang.UnsupportedClassVersionError大调/小调51.0的Kamon

Question

我试着用kamon把数据发送到datadog。我的设置如下：

io.kamon
kamon-core_2.10
0.3.1


io.kamon
kamon-datadog_2.10
0.3.1

<SCALA_MAJOR>2.10</SCALA_MAJOR>
<SCALA_VERSION>2.10.3</SCALA_VERSION>
<AKKA_VERSION>2.3.2</AKKA_VERSION>

JDK 1.6

Datadog Agent Version: 4.4.0

在akka初创公司，我得到了以下例外：

Exception in thread "main" java.lang.UnsupportedClassVersionError:                    kamon/util/GlobPathFilter : Unsupported major.minor version 51.0

默认情况下，Kamon是为Java1.7构建的。现在，它将支持1.6
