Do you by chance have the coverage file from the job? It would make it easier to debug

[f33r0]

unfortunately I can't publish

[f33r0]

after using the new publishing command I get the error:

Also: org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: 37c0b962-d0b3-4c35-9fe4-f03d617c2f2c
java.lang.IllegalArgumentException: There is already a child [METHOD] <hyper::client::dispatch::Receiver<http::request::Request<hyper::body::body::Body>, http::response ::Response<hyper::body::body::Body>>>::close <0> with the name <hyper::client::dispatch::Receiver<http::request::Request<hyper::body ::body::Body>, http::response::Response<hyper::body::body::Body>>>::close in [CLASS] dispatch <7, LINE: 35.71% (10/28)>

is it still possible to describe a more detailed README for using the plugin in jenkins?

I have a long cobertura report.

How I can reduce memory usage by plugin??
