提问by midNight

当我执行命令protoc --version 时，它会产生
libprotoc 2.5.0

as output.
作为输出。
but Once I have pulled code from git and when I try to compile it using Maven3, the proto module throws error saying,
但是一旦我从 git 中提取代码并且当我尝试使用 Maven3 编译它时，proto 模块就会抛出错误说，
protoc failed error: /bin/sh: protoc: command not found
protoc 失败错误：/bin/sh: protoc: command not found
I refereed many blogs and also did try to change my bashrc path as follows,
我参考了很多博客，也确实尝试如下更改我的 bashrc 路径，
export JAVA_HOME=/opt/java/jdk1.7.0_67
export PATH=$PATH:/opt/java/jdk1.7.0_67/bin
export PATH=$PATH:/usr/local/lib
导出 JAVA_HOME=/opt/java/jdk1.7.0_67
导出 PATH=$PATH:/opt/java/jdk1.7.0_67/bin
导出 PATH=$PATH:/usr/local/lib
but if I execute,
但如果我执行，
sudo yum install protobuf-compiler
须藤 yum 安装 protobuf 编译器
it installs protobuf2.3 compiler and this particular error gets solved. But since my pom file has protobuf 2.5.0, java abstract method errorarises during the next compilation. I'm stuck on how to proceed. I've spend many hrs in it, so any help is much appreciated.
它安装了 protobuf2.3 编译器，这个特定的错误得到了解决。但是由于我的pom文件是protobuf 2.5.0，下次编译的时候会出现java抽象方法错误。我被困在如何继续。我在里面花了很多时间，所以非常感谢任何帮助。

EDIT: I solved it. I copied protoc file from /usr/local/lib to /usr/bin
编辑：我解决了它。我将 protoc 文件从 /usr/local/lib 复制到 /usr/bin
and it solved it. A silly mistake :P
它解决了它。一个愚蠢的错误：P

You should run 'sudo ldconfig' to finish the installation.
您应该运行“sudo ldconfig”来完成安装。
I guessed you set LD_LIBRARY_PATH to add /usr/local/lib in your environment setting. And it doesn't take effect when building project with maven/sbt and other build tools.
我猜你设置了 LD_LIBRARY_PATH 来在你的环境设置中添加 /usr/local/lib 。并且在使用maven/sbt等构建工具构建项目时不生效。
