JaCoCo在设置log4j.configurationFactory
系统属性后停止工作。

Exception in thread "main"
我已经阅读过类似于JaCoCo和JDK 1.8的错误,但它已经在JaCoCo 0.7.7中得到了解决。
VM参数的定义如下:
-Dlog4j.configurationFactory=mytest.CustomConfigurationFactory
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
-Dcom.sun.management.jmxremote.rmi.port=9090
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=9090
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=localhost
-javaagent:/path/jacocoagent.jar=destfile=C:/TEMP/jacoco.exec,jmx=true
我正在使用:
有谁知道如何解决它?
答案 0 :(得分:4)
正如JaCoCo users mailing list中所回答:
JaCoCo(截至目前为0.7.9的最新版本),使用Log4j JDK日志适配器时JMX和Logging以及JaCoCo代理注册JMX MBean之间的交互似乎存在实际问题。在此期间,更深入的调查需要一些时间
JaCoCo代理应该配置为不注册JMX MBean,即没有jxm=true
或等同于jxm=false
(-javaagent:jacocoagent.jar=jmx=false
),应该注意JMX不是只有远程连接到JaCoCo代理的选项 - output=tcpserver
output=tcpclient
和‑Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
不应使用Log4j JDK记录适配器,即不使用# This solution only prints unique elements in df1 which are not in df2
np.setdiff1d(df1,df2)
Out[236]: array(['b0002'], dtype=object)
这是一张修复JaCoCo方面的门票,解释了会发生什么 - have a look
