Hello,
We have a test instance for lifecycle with an autosigned certificate.
I try to launch maven plugin on a my projet and i can’t avoid the certificate check with -Dmaven.wagon.http.ssl.insecure=true option
> mvn clean install com.sonatype.clm:clm-maven-plugin:evaluate -Dclm.serverUrl=[https://myServer](https://myServer) -Dclm.applicationId=app\_id -Dmaven.wagon.http.ssl.insecure=false
give me this error
> [ERROR] Failed to execute goal com.sonatype.clm:clm-maven-plugin:2.31.1-01:evaluate (default-cli) on project myproject: Could not communicate with IQ Server: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target → [Help 1]
is there any option to set on command line to avoid certificate validation ?

You need to set that in MAVEN\_OPTS environment variable, see here:

i try :
> export MAVEN\_OPTS=“-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true”
this is recorded
> env | grep MAVEN\_OPTS
> MAVEN\_OPTS=-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true
still have the same error. i also see it inside the log
> [DEBUG] properties used … env.MAVEN\_OPTS= -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true … maven.wagon.http.ssl.insecure=true …
I also try to put into the plugin configuration without success :
> ```
> com.sonatype.clm
> clm-maven-plugin
> 2.31.1-01
>
> true
> true
> true
