mvn在Postgres 9.5上的PL/Java清洁安装失败

Question

我正在Postgres 9.5上安装PL/Java。

我的设置是在CentOS6.5上使用1.8.0_92的Postgres 9.5

我的Postgres安装是通过这些yum-包完成的：

postgresql95
postgresql95-devel
postgresql95-libs
postgresql95-server

以下是我迄今所采取的步骤的总结：

su - postgres
git clone https://github.com/tada/pljava
git checkout V1_5_0
mvn clean install

在我看到这个之前，这似乎是可行的：

我欢迎关于如何最好地调试这一点的任何线索和/或意见，以便mvn干净安装将运行无错误。

我从root运行了一个shell命令来修复它：

yum install openssl-devel

修好了。耶！
