Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unl

Jenkins验证应用失败。控制台错误输出信息如下：

查询网络的解决办法：

1.可能内存不足

2.执行命令ulimit -c unlimited

但是似乎都不是该原因。可能是因为项目启动太多。内存不足。所以笔者尝试清内存，杀进程。

效果似乎很明显：降下来了

 

所以大家可以试试 查找相关端口进程：netstat -anp|grep 9300

直接kill -9  pid 

 

但是好像不是这个原因，因为我本地使用package都失败了，执行了好多test方法

所以我尝试跳过执行测试用例

使用命令：mvn clean package -DskipTests
