Proxy Configuration

With dependency-check 9.x the proxy configuration is unfortunately in transition and, if required, will likely need to be configured twice.

Java Properties

The go-forward proxy configuration is done using Apache HTTPClient system property proxy configuration which can be set using an environment variable JAVA_TOOL_OPTIONS. See https://hc.apache.org/httpcomponents-client-5.4.x/current/httpclient5/apidocs/org/apache/hc/client5/http/impl/classic/HttpClientBuilder.html for more information. The recommended properties that can be configured are:

  • https.proxyHost
  • https.proxyPort
  • https.proxyUser
  • https.proxyPassword
  • http.nonProxyHosts

And in case of legacy URLs that are not (yet) exposing on https:

  • http.proxyHost
  • http.proxyPort
  • http.proxyUser
  • http.proxyPassword

As example configuration would be:

export JAVA_TOOL_OPTIONS=-Dhttps.proxyHost=my-proxy.internal -Dhttps.proxyPort=8083

If you have some custom internal URLs that are on plain http, but do require use of the proxy you should also add the http.* properties for the proxy.

export JAVA_TOOL_OPTIONS=-Dhttps.proxyHost=my-proxy.internal -Dhttps.proxyPort=8083 -Dhttp.proxyHost=my-proxy.internal -Dhttp.proxyPort=8083

Legacy configuration

Legacy proxy configuration can be configured in any of the dependency-check integrations (CLI, Maven, Gradle, Ant, Jenkins). See the configuration settings for each:

Certificate Errors

In some cases if you setup a proxy the connection may still fail due to certificate errors (see the log file from dependency-check). If you know which cert it's failing on (either your proxy or NVD/CVE) you can either add the certificate itself or the signing chain to your trust store. If you don't have access to modify the system trust store (in $JAVA_HOME/lib/security/cacerts) you can copy it elsewhere and import it using keytool, then specify that trust store on the command line (mvn -Djavax.net.ssl.trustStore=/path/to/cacerts) or if you need to always have that set, you can set the environment variable JAVA_TOOL_OPTIONS to have -Djavax.net.ssl.trustStore=/path/to/cacerts.

If trying the above and it still fails please open a ticket in the github repo.
