windows下使用maven编译flume

本文讲解如何在windows下使用maven编译,以及如何在windows下执行

1、下载 flume 的源文件,地址:http://www.apache.org/dyn/closer.cgi/flume/1.5.0.1/apache-flume-1.5.0.1-src.tar.gz

2、本地安装maven环境

3、切换到源文件路径下执行:mvn clean

                                                 mvn package -DskipTests    // -DskipTests 使编译跳过测试,不然会报错

 

4、提示编译成功后,会在*\flume-ng-dist\target 目录下产生文件:apache-flume-1.5.0.1-bin、 apache-flume-1.5.0.1-bin.tar.gz、apache-flume-1.5.0.1-src、apache-flume-1.5.0.1-src.tar.gz,apache-flume-1.5.0.1-bin下的文件就可以用了

5、编译后,发现生成的仍然是linux下的脚本,无法再windows下执行,没关系,只要自己加上windows的执行脚本就行了,简单的脚本示例如下:

 

rem flume 1.5.0.1 windows script.
set FLUME_HOME=D:\java\apache-flume-1.5.0.1-bin
set JAVA="D:\java\JDK6_2\bin\java.exe"
set JAVA_OPTS=-Xmx60m
set CONF=%FLUME_HOME%\conf\kafka.properties
set AGENT=kafka
%JAVA%  %JAVA_OPTS%  -Dlog4j.configuration=file:///%FLUME_HOME%\conf\log4j.properties -cp "%FLUME_HOME%\lib\*"
org.apache.flume.node.Application  -f %CONF%   -n %AGENT%

 

 

6、可能遇到的问题:

内存溢出
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.
3.2:testCompile (default-testCompile) on project flume-ng-elasticsearch-sink: Co
mpilation failure
[ERROR] Failure executing javac, but could not parse the error:
[ERROR]
[ERROR]
[ERROR] 系统资源不足。
[ERROR] 有关详细信息, 请参阅以下堆栈跟踪。
[ERROR] java.lang.OutOfMemoryError: PermGen space
[ERROR] at java.lang.ClassLoader.defineClass1(Native Method)
[ERROR] at java.lang.ClassLoader.defineClass(ClassLoader.java:791)
[ERROR] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:14
2)
……

当Maven项目很大时,maven运行需要很大的内存,在默认配置下,就可能遇到java的堆溢出,这时指定分配内存大小

windows环境下:找到maven目录\bin\mvn.bat文件,编辑,在行

@REM set MAVEN_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE... 下设置

set MAVEN_OPTS= -Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m

linux环境下:设置环境变量,编辑/etc/profile 增加

export  MAVEN_OPTS=-Xmx512m

这个包比较大,重试几把就行了

这个问题搞了好一会,试了几种方法,没搞定。

发现它是对flume-ng-morphline-solr-sink的编译,需要依赖 ua_parser:ua-parser:jar:1.3.0,变通一点,先绕过它再说,在*\apache-flume-1.5.0.1-src\flume-ng-sinks\pom.xml 中,

注释掉 <module>flume-ng-morphline-solr-sink</module>,最后可以愉快的看到 [INFO] BUILD SUCCESS 啦
