Maven - 将代码发布到 GitHub 时出错（推送后挂起）

我试图跑动目标，它在推动后挂起。任何想法，我可能做错了什么？mvn release:prepare

以下是我的pom的SCM部分.xml：

<scm>
    <connection>scm:git:git://github.com/tleese22/my-app.git</connection>
    <developerConnection>scm:git:git@github.com:tleese22/my-app.git</developerConnection>
    <url>http://github.com/tleese22/my-app</url>
</scm>

...

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin</artifactId>
    <version>2.0</version>
</plugin>

以下是我的.git/config：

[core]
    repositoryformatversion = 0
    filemode = true
    logallrefupdates = true
    bare = false
[branch "master"]
    remote = origin
    merge = refs/heads/master
[remote "origin"]
    url = git@github.com:tleese22/my-app.git
    fetch = +refs/heads/*:refs/remotes/origin/*
    pushurl = git@github.com:tleese22/my-app.git

以下是 git 显示原点的结果：

$ git remote show origin
Enter passphrase for key '/c/Users/Taylor Leese/.ssh/id_rsa':
* remote origin
  Fetch URL: git@github.com:tleese22/my-app.git
  Push  URL: git@github.com:tleese22/my-app.git
  HEAD branch: master
  Remote branches:
    gh-pages new (next fetch will store in remotes/origin)
    master   new (next fetch will store in remotes/origin)
  Local branch configured for 'git pull':
    master merges with remote master
  Local ref configured for 'git push':
    master pushes to master (up to date)

$ git status
# On branch master
nothing to commit (working directory clean)
