kakfa源码编译打包

kakfa项目编译：

cd /home/zhaofuxin/workspace/kafka-0.8.2.1-src

./gradlew releaseTarGz

会出现如下异常：

zhaofuxin@ubuntu-machine:~/workspace/kafka-0.8.2.1-src$ ./gradlew releaseTarGz Downloading https://services.gradle.org/distributions/gradle-2.0-bin.zip Exception in thread "main" javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake      at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:946)      at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1312)      at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1339)      at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1323)      at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:563)      at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185)      at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1300)      at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)      at org.gradle.wrapper.Download.downloadInternal(Download.java:58)      at org.gradle.wrapper.Download.download(Download.java:44)      at org.gradle.wrapper.Install$1.call(Install.java:61)      at org.gradle.wrapper.Install$1.call(Install.java:48)      at org.gradle.wrapper.ExclusiveFileAccessManager.access(ExclusiveFileAccessManager.java:65)      at org.gradle.wrapper.Install.createDist(Install.java:48)      at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:128)      at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61) Caused by: java.io.EOFException: SSL peer shut down incorrectly      at sun.security.ssl.InputRecord.read(InputRecord.java:482)      at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:927)      ... 15 more

在 Downloading https://services.gradle.org/distributions/gradle-2.0-bin.zip 过程中会出现如上异常

https://services.gradle.org/distributions/gradle-2.0-bin.zip 的URL地址配置在/home/zhaofuxin/workspace/kafka-0.8.2.1-src/gradle/wrapper/gradle-wrapper.properties文件中。

是网络原因，多试几次后，就可以正常下

载了，有一个疑问，gradle已经安装了，为什么还会下载gradle-2.0-bin.zip文件，这个文件是什么用，下载到那个位置了？

从日志可以看出下载的位置是：/home/zhaofuxin/.gradle/wrapper/dists/gradle-2.0-bin

Building project 'core' with Scala version 2.10.4

cd /home/zhaofuxin/.gradle/wrapper/dists/gradle-2.0-bin/

发现下面有 gradle-2.0-bin.zip.lck 和gradle-2.0-bin.zip.ok 两个空的标示文件，所有当网络下载较慢是，可以把文件直接放到这个目录下，减少下载的耗时。

相关文件可以到我的共享地址下载：

当出现如下标示时编译成功：

编译成功后， 在core/build/distributions/里面生成kafka_2.10-0.8.2.1.tgz文件，这个和从网上下载的一样，可以直接用。

./gradlew releaseTarGzAll -x signArchives

这时候将会编译成功（在编译的过程中将会出现很多的）。在编译的过程中，我们也可以指定对应的Scala版本进行编译：

./gradlew -PscalaVersion=2.10.3 releaseTarGz -x signArchives

=========================

kafka源码的编译：

gradle jar_core_2_10_4 --stacktrace

#使用gradle构建kafka项目

gradle build -x test

其中的-x test表示跳过unit test
