求一个 events-log.jar 插件用于 Jenkins 与 Gerrit“通信“

[flyfowl]

最近在搭建 Jenkins+Gerrit+Git，Gerrit+Git 已经配置好了，设置 Jenkins 添加 Gerrit 服务器时，需要在 Gerrit 上添加一个名叫 events-log.jar 的插件，这个插件不是标配的，需要自行编译，我在网上找了好久都没找到现成的，尝试编译了一天多各种错误，没接触过 buck、bazel 之类的命令，好不容易编译出 buck，再用 buck build 插件各种出错，event-log 各个版本也不太一样……

有童鞋能帮忙发一个这个插件，或者帮忙编译一个吗，如果你对这类命令很熟悉的话，Gerrit 用的是 2.14.3

附一个对编译可能有帮助的链接： https://stackoverflow.com/questions/31116188/buck-build-failing-for-events-logs-gerrit-plugin-jar

时过半年，配置 Jenkins 又用到了这个，方便大家使用，附上博客下载地址：

终于 TMD 编译出来了，记录一下，方便后人：）

按照如下顺序操作，一定要按顺序：
git clone https://gerrit.googlesource.com/plugins/events-log
cd events-log
git checkout stable-2.12
git clone https://gerrit.googlesource.com/bucklets
~/buck/bin/buck build plugin

这样就好了，bucklets 要在 events-log 目录下，建立软链接 build 会报错：

BUILD FAILED: Target //bucklets/tools:download_file contains input files under a path which contains a symbolic link ({bucklets=/home/gerrit2/gerrit_src/bucklets}). To resolve this, use separate rules and declare dependencies instead of using symbolic links.
If the symlink points to a read-only filesystem, you can specify it in the project.read_only_paths .buckconfig setting. Buck will assume files under that path will never change.

This error happened while trying to get dependency '//bucklets/tools:download_file' of target '//lib:gson__download_bin'

删掉软链接也会报错：
BUILD FAILED: Buck wasn't able to parse /home/gerrit2/gerrit_src/events-log/BUCK:
IOError: [Errno 2] No such file or directory: '/home/gerrit2/gerrit_src/events-log/bucklets/gerrit_plugin.bucklet'

TMD 最后我把 bucklets 目录放到 events-log 目录下，完美编译出来了

如果报错：
BUILD FAILED: //:events-log__plugin failed:
javac -source 7 -target 7 -sourcepath -g -proc:none -d /home/gerrit2/gerrit_src/events-log/buck-out/bin/lib__events-log__plugin__classes -classpath /home/gerrit2/gerrit_src/events-log/buck-out/gen/lib/__gson__/gson-2.3.1.jar:/home/gerrit2/gerrit_src/events-log/buck-out/gen/lib/commons/__dbcp__/commons-dbcp-1.4.jar:/home/gerrit2/gerrit_src/events-log/buck-out/gen/lib/commons/__pool__/commons-pool-1.5.5.jar:/home/gerrit2/gerrit_src/events-log/buck-out/gen/lib/gerrit/__plugin-api__/gerrit-plugin-api-2.12.jar @buck-out/gen/__events-log__plugin__srcs
No system compiler found. Did you install the JRE instead of the JDK?
那么重新设置一下 java 编译器 使用命令“ update-alternatives --config java ”

感谢，实测有用，这个东西的确太难编译了
