मैंने केवल मावेन को डाउनलोड किया और "पांच मिनटों में मावेन" पृष्ठ ( http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html ) पर मिली साधारण कमांड को चलाने की कोशिश कर रहा था । यह आज्ञा है:
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
जब मैं इसे चलाता हूं तो मुझे एसएसएल प्रमाणपत्र के साथ एक त्रुटि मिलती है और https://repo.maven.apache.org/maven2 पर केंद्रीय मावेन भंडार से डाउनलोड नहीं किया जा सकता है । त्रुटि "SunCertPathBuilderException: अनुरोधित लक्ष्य के लिए मान्य प्रमाणन पथ खोजने में असमर्थ है"।
मैं एक कॉर्पोरेट फ़ायरवॉल के पीछे बैठा हूं और दोनों के लिए प्रॉक्सी सेटिंग्स को सही ढंग से कॉन्फ़िगर किया है http
और फ़ाइल के https
माध्यम से एक्सेस किया settings.xml
है। मुझे संदेह है कि जो कोई भी मावेन को डाउनलोड करता है और पहली बार इसे चलाता है, उसे मावेन रिपॉजिटरी के एसएसएल प्रमाणपत्र को आयात करना पड़ता है, इसलिए समस्या प्रॉक्सी के साथ होनी चाहिए। क्या किसी को इसका कोई अनुभव है?
यहां पूर्ण डिबग मोड (-X) में स्टैक ट्रेस दिया गया है:
