我正在使用nexus-3.0.1 OSS（使用默認設置）和maven 3.3.9來執行此link中提到的發佈。使用maven-release-plugin失敗的maven發佈到nexus 3.0.1
我的pom.xml看起來象下面這樣： -

我settings.xml看起來象下面這樣： -

</settings>
但每當我執行mvn release:clean它與下面的錯誤而失敗： -
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.4.1:clean (default-cli) on project git-demo: Execution default-cli of goal org.apache.maven.plugins:maven-release-plugin:2.4.1:clean failed: Plugin org.apache.maven.plugins:maven-release-plugin:2.4.1 or one of its dependencies could not be resolved: Could not transfer artifact org.codehaus.groovy:groovy-all:jar:1.7.6 from/to central (https://repo.maven.apache.org/maven2): GET request of: org/codehaus/groovy/groovy-all/1.7.6/groovy-all-1.7.6.jar from central failed: Connection reset -> [Help 1]
但是，一切正常工作mvn clean deploy，我能夠在nexus中的快照回購中看到jar。
下面是行家全輸出，同時執行mvn release:clean： -

有人可以讓我知道了什麼錯誤？
是的，這是一個網絡問題。我對你答案的最後部分有疑問。我添加了' true'。不應該跳過舞臺？ –

除非你有Nexus PRO，否則根本沒有必要配置這個插件，因爲OSS版本沒有與它通信的Staging API。 – TheKaptain
雖然Nexus Staging插件添加了一些部署功能，即使您不使用Nexus Pro也是如此。你必須使用Nexus。但是，我認爲，它會允許像構建多個工件那樣的東西，然後只有在所有構建都正確的情況下才發佈它們。可能有更多的功能。 –
