gradle-nexus-letsencrypt.sh

#!/bin/sh

# Download the certificate you need from the website
openssl s_client -connect my-nexus-website.com:443 > www.crt

# Go into the certificate and delete everything before -------START ----- and after ------ END ------

# Create your own keystore to use for this certificate -- add as many as you want
sudo keytool -trustcacerts -keystore cacerts -storepass cacerts -noprompt -importcert -alias www -file www.crt 

# Copy that to your android project
cp cacerts ~/my/android/project

# Add this to your build.gradle or android.gradle (if it's separate)
android {
    signingConfigs {
        release {
            storeFile file("cacerts")
            storePassword "cacerts"
            keyAlias "www"
            keyPassword ""
        }
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}
