Problems using Maven and SSL behind proxy

Question

I just downloaded Maven and was trying to run the simple command found on the  Maven in Five Minutes  page  http   maven apache org guides getting-started maven-in-five-minutes html   This is the command   mvn archetype generate -DgroupId com mycompany app -DartifactId my-app -DarchetypeArtifactId maven-archetype-quickstart -DinteractiveMode false   When I run it I get an error with SSL certificate and cannot download from the central Maven repository at https   repo maven apache org maven2  The error is  SunCertPathBuilderException  unable to find valid certification path to requested target     I am sitting behind a corporate firewall and have correctly configured the proxy settings for both http and https access via the settings xml file  I doubt that everyone who downloads Maven and runs it for the first time has to import the SSL certificate of the Maven repository  so the problem must be with the proxy  Does anyone have any experience with this   Here s the stack trace in full debug mode  -X     mvn archetype generate -DgroupId com mycompany app -DartifactId my-app -DarchetypeArtifactId maven-archetype-quickstart -DinteractiveMode false  Apache Maven 3 2

I ran into this problem in the same situation  and I wrote up a detailed answer to a related question on stack overflow explaining how to more easily modify the system s cacerts using a GUI tool   I think it s a little bit better than using a one-off keystore for a specific project or modifying the settings for maven  which may cause trouble down the road

Step 1  GET the contents of the Certificate of the website  you want to have it imported as a trusted root     keytool -printcert -rfc -sslserver maven 2xoffice com   -----BEGIN CERTIFICATE----- MIIFNTCCBB2gAwIBAgIHJ73QrVnyJjANBgkqhkiG9w0BAQsFADCBtDELMAkGA1UEBhMCVVMxEDAO     -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- MIIE3jCCA8agAwIBAgICAwEwDQYJKoZIhvcNAQEFBQAwYzELMAkGA1UEBhMCVVMxITAfBgNVBAoT     -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- MIIEADCCAuigAwIBAgIBADANBgkqhkiG9w0BAQUFADBjMQswCQYDVQQGEwJVUzEhMB8GA1UEChMY     -----END CERTIFICATE----- The -rfc option outputs the certificate chain in PEM-encoded format for easy import back into a keystore    Step 2  Save the whole thing  including the BEGIN CERTIFICATE and END CERTIFICATE lines  which are significant in this case  as godaddyg2 pem and imported it into my trust store via   Step 3  Import the certificate in the keystore  java trusted key store     keytool -importcert -file   godaddyg2 pem -keystore  JRE LIB lib security cacerts

Even though I was putting the certificates in cacerts  I was still getting the error  Turns our I was putting them in jre  not in jdk jre   There are two keystores  keep that in mind

You can import the SSL cert manually and just add it to the keystore   For linux users    Syntax      keytool -trustcacerts -keystore  jre lib security cacerts   -storepass changeit -importcert -alias nexus -file    Example        keytool -trustcacerts -keystore    Library Java JavaVirtualMachines jdk1 8 0 144 jdk Contents Home jre lib security cacerts   -storepass changeit -importcert -alias nexus -file   Downloads abc com-ssl crt

Update  I just stumbled on this bug report   https   bugs launchpad net ubuntu  source ca-certificates-java  bug 1396760  It appears to be the cause of our problems here   Something with ca-certificates-java encountering an error and not fully populating cacerts   For me  this started happening after I upgraded to 15 10 and this bug probably occurred during that process   The workaround is to execute the following command      sudo  var lib dpkg info ca-certificates-java postinst configure   If you check the contents of the keystore  as in my original answer   you ll now see a whole bunch more  including the needed DigiCert Global Root CA   If you went through the process in my original answer  you can clean up the key we added by running this command  assuming you did not specify a different alias       sudo keytool -delete -alias mykey -keystore  etc ssl certs java cacerts   Maven will now work fine     Original Answer  I d just like to expand on Andy s answer about adding the certificate and specifying a keystore   That got me started  and combined with information elsewhere I was able to understand the problem and find another  better   solution   Andy s answer specifies a new keystore with the Maven cert specifically   Here  I m going a bit more broad and adding the root certificate to the default java truststore   This allows me to use mvn  and other java stuff  without specifying a keystore   For reference my OS is Ubuntu 15 10 with Maven 3 3 3   Basically  the default java truststore in this setup does not trust the root certificate of the Maven repo  DigiCert Global Root CA   so it needs to be added   I found it here and downloaded   https   www digicert com digicert-root-certificates htm  Then I found the default truststore location  which resides here       etc ssl certs java cacerts   You can see what certs are currently in there by running this command      keytool -list -keystore  etc ssl certs java cacerts   When prompted  the default keystore password is  changeit   but nobody ever does    In my setup  the fingerprint of  DigiCert Global Root CA  did not exist  DigiCert calls it  thumbprint  in the link above    So here s how to add it      sudo keytool -import -file DigiCertGlobalRootCA crt -keystore    etc ssl certs java cacerts   This should prompt if you trust the cert  say yes   Use keytool -list again to verify that the key exists   I didn t bother to specify an alias  -alias   so it ended up like this      mykey  Dec 2  2015  trustedCertEntry  Certificate fingerprint  SHA1     A8 98 5D 3A 65 E5 E5 C4 B2 D7 D6 6D 40 C6 DD 2F B1 9C 54 36   Then I was able to run mvn commands as normal  no need to specify keystore

I actually had the same problem   when I run      mvn clean package    on my maven project  I get this certificate error by the maven tool   I followed  Andy  s Answer till the point where I downloaded the  cer file  after that the rest of the answer didn t work for me but I did the following I am running on Linux Debian machine   first of all  run      keytool -list -keystore  Java path   jre lib security cacerts     for example in my case it is      keytool -list -keystore  usr lib jvm jdk-8-oracle-arm32-vfp-hflt jre lib security cacerts   if it asks about the password  just hit enter   this command is supposed to list all the ssl certificates accepted by the java  when I ran this command  in my case I got 93 certificates for example   Now add the downloaded file  cer to the cacerts file by running the following command      sudo keytool -importcert -file  home hal Public certificate file downloaded cer -keystore  usr lib jvm jdk-8-oracle-arm32-vfp-hflt jre security cacerts   write your sudo password then it will ask you about the keystore password  the default one is changeit  then say y that you trust this certificate   if you run the command      keytool -list -keystore  usr lib jvm jdk-8-oracle-arm32-vfp-hflt jre lib security cacerts   once again  in my case  I got 94 contents of the cacerts file  it means  it was added successfully

The fact is that your maven plugin try to connect to an https remote repository  e g https   repo maven apache org maven2    This is a new SSL connectivity for Maven Central was made available in august  2014    So please  can you verify that your settings xml has the correct configuration        lt settings gt     lt activeProfiles gt       lt  --make the profile active all the time -- gt       lt activeProfile gt securecentral lt  activeProfile gt     lt  activeProfiles gt     lt profiles gt       lt profile gt         lt id gt securecentral lt  id gt         lt  --Override the repository  and pluginRepository   central  from the          Maven Super POM -- gt         lt repositories gt           lt repository gt             lt id gt central lt  id gt             lt url gt http   repo1 maven org maven2 lt  url gt             lt releases gt               lt enabled gt true lt  enabled gt             lt  releases gt           lt  repository gt         lt  repositories gt         lt pluginRepositories gt           lt pluginRepository gt             lt id gt central lt  id gt             lt url gt http   repo1 maven org maven2 lt  url gt             lt releases gt               lt enabled gt true lt  enabled gt             lt  releases gt           lt  pluginRepository gt         lt  pluginRepositories gt       lt  profile gt     lt  profiles gt   lt  settings gt    You can alternatively use the simple http maven repository like this    lt pluginRepositories gt       lt pluginRepository gt         lt id gt central lt  id gt         lt name gt Maven Plugin Repository lt  name gt         lt url gt http   repo1 maven org maven2 lt  url gt         lt layout gt default lt  layout gt         lt snapshots gt           lt enabled gt false lt  enabled gt         lt  snapshots gt         lt releases gt           lt updatePolicy gt never lt  updatePolicy gt         lt  releases gt       lt  pluginRepository gt     lt  pluginRepositories gt    Please let me know if my solution works     J

It happens because your maven plugin try to connect to an HTTPS remote repository  https   repo maven apache org maven2  or  https   repo1 maven apache org   Some time ago  you could to change these URL s to use HTTP instead use HTTPS  but since January 15th 2020  these URL s doesn t work any more  only the HTTPS URL s  As an easy way to fix this problem  you can use the insecure Maven URL in the settings xml file  So  you need to change ALL of yours references above mencioned to  http   insecure repo1 maven org maven2  TIP  Your JAVA HOME variable always needs to point to your JDK path  not to your JRE path  for example   quot C  Program Files Java jdk1 7 0 80 quot

ymptom  After configuring Nexus to serve SSL maven builds fail with  quot peer not authenticated quot  or  quot PKIX path building failed quot   This is usually caused by using a self signed SSL certificate on Nexus  Java does not consider these to be a valid certificates  and will not allow connecting to server s running them by default  You have a few choices here to fix this   Add the public certificate of the Nexus server to the trust store of the Java running Maven Get the certificate on Nexus signed by a root certificate authority such as Verisign Tell Maven to accept the certificate even though it isn t signed  For option 1 you can use the keytool command and follow the steps in the below article  Explicitly Trusting a Self-Signed or Private Certificate in a Java Based Client For option 3  invoke Maven with  quot -Dmaven wagon http ssl insecure true quot   If the host name configured in the certificate doesn t match the host name Nexus is running on you may also need to add  quot -Dmaven wagon http ssl allowall true quot   Note  These additional parameters are initialized in static initializers  so they have to be passed in via the MAVEN OPTS environment variable   Passing them on the command line to Maven will not work  See here for more information  http   maven apache org wagon wagon-providers wagon-http

I was getting the same error about the SSL certificate when Maven tried to download the necessary modules automatically   As a remedy  I was attempting to implement Luke s answer above  but found that the DigiCert Global Root CA certificate is already in Java s trusted keystore  What helped me was adding  JAVA HOME  bin to the Path variable  I am running Windows   And  JAVA HOME  is a JDK location  not just a JRE location  since Maven needs a JDK  I am not certain why it helped  but it did  I am absolutely sure that this was the only thing I changed

The issue  I got is Earlier  I was using jdk 1 8 0 31 with certificate installed  I switched to jdk 1 8 0 191 but did not install certificate   But  my projects were working fine  I realized that their dependencies were downloaded already  So  they would only compile and package those projects  But  this did not work for new maven projects as their dependencies were not downloaded earlier   Solution     Switch to earlier jdk version which had certificate already installed  for your new project and do clean install Download certificate again for the new jdk version that you have recently switched to and then do clean install

The answer above is a good working solution  but here s how to do it if you want to use the SSL repo    Use a browser  I used IE  to go to https   repo maven apache org    Click on lock icon and choose  View Certificate  Go to the  Details  tab and choose  Save to File  Choose type  Base 64 X 509   CER   and save it somewhere  Now open a command prompt and type  use your own paths    keytool -import -file C  temp mavenCert cer -keystore C  temp mavenKeystore Now you can run the command again with the parameter   -Djavax net ssl trustStore C  temp mavenKeystore Under linux use absolute path  -Djavax net ssl trustStore  tmp mavenKeystore  otherwise this will happen Like this   mvn archetype generate -DgroupId com mycompany app -DartifactId my-app -DarchetypeArtifactId maven-archetype-quickstart -DinteractiveMode false -Djavax net ssl trustStore C  temp mavenKeystore   Optional   You can use the MAVEN OPTS environment variable so you don t have to worry about it again  See more info on the MAVEN OPTS variable here
