试图在Scala 2.9.2上构建和运行ApacheKafka 0.8，但没有成功

正如主题描述中所述，我正在尝试使用Scala 2.9.2运行

Kafka 0.8

我能够使用

0.8

（）的快速入门获得一个工作版本，但默认情况下它是根据

scala2.8.0

编译的

我试图修改步骤

./sbt package 

到

它编译时没有错误，但在启动过程中，它抱怨找不到主类

/tmp/kafka-8-test/kafka[0.8]$ bin/kafka-server-start.sh onfig/server1.properties
Error: Could not find or load main class kafka.Kafka

---

非常感谢您的帮助。

问题在于bin/kafka-server-start.sh脚本使用bin/kafka-run-class.sh来执行生成的jar文件

此脚本具有硬编码版本，因此您需要按如下方式对其进行自定义：

...
library=$(echo "$ivyPath/org.scala-lang/scala-library/jars/scala-library-2.9.2.jar")
CLASSPATH=$CLASSPATH:$library

compiler=~$(echo "$ivyPath/org.scala-lang/scala-compiler/jars/scala-compiler-2.9.2.jar")
CLASSPATH=$CLASSPATH:$compiler

log4j=$(echo "$ivyPath/log4j/log4j/jars/log4j-1.2.15.jar")
CLASSPATH=$CLASSPATH:$log4j

slf=$(echo "$ivyPath/org.slf4j/slf4j-api/jars/slf4j-api-1.6.4.jar")
CLASSPATH=$CLASSPATH:$slf

zookeeper=$(echo "$ivyPath/org.apache.zookeeper/zookeeper/jars/zookeeper-3.3.4.jar")
CLASSPATH=$CLASSPATH:$zookeeper

jopt=$(echo "$ivyPath/net.sf.jopt-simple/jopt-simple/jars/jopt-simple-3.2.jar")
CLASSPATH=$CLASSPATH:$jopt

for file in $base_dir/core/target/scala-2.9.2/*.jar;
do
  CLASSPATH=$CLASSPATH:$file
done

for file in $base_dir/core/lib/*.jar;
do
  CLASSPATH=$CLASSPATH:$file
done

for file in $base_dir/perf/target/scala-2.9.2/kafka*.jar;
do
  CLASSPATH=$CLASSPATH:$file
done
...

kafka run class.sh

硬编码为Scala 2.8.0。您可以按照prenomenon的建议将2.8.0更改为2.9.2

这对我很有用：

• Linux | Unix

  sed-i“s/2.8.0/2.9.2/g”bin/kafka run class.sh

• 马科斯

  sed-i.bak“s/2.8.0/2.9.2/g”bin/kafka run class.sh

对于最新版本的卡夫卡0.8.1.1和gradlew，“SCALA_版本”是脚本中的一个变量

SCALA_版本=2.10.4

但是，在以下情况下，出现了一些问题：

``` ./gradlew-PscalaVersion=2.10.4罐

```

其中一个文件没有2.10.4部分，但只有2.10部分：

彼得_v@trusty64：~/data/kafka/kafka-0.8.1.1-src$find-名称'*.jar'

通过复制到2.10.4名称作为解决方法，卡夫卡正确启动

```

cp core/build/libs/kafka_2.10-0.8.1.1.jar core/build/libs/kafka_2.10.4-0.8.1.1.jar

```

要用Scala 2.9.2构建Kafka，我必须将Scala版本添加到每个构建命令中，比如

/sbt“++2.9.2更新”

/sbt“++2.9.2包”/sbt“++2.9.2 make pom”/code>/sbt“++2.9.2程序集包依赖项”

CLASSPATH=$CLASSPATH:$compiler

CLASSPATH=$CLASSPATH:$log4j
