Question

我正在尝试将Objectify添加到我的Google App Engine项目中。我按照https://code.google.com/p/objectify-appengine/wiki/MavenRepository上的说明进行操作，该说明为我的pom.xml添加依赖项。

我将依赖项复制并粘贴到我的pom.xml中，但是当我执行mvn clean install时出现以下错误：

问题的解决方案是复制并粘贴然后修改版本号。以下是https://code.google.com/p/objectify-appengine/wiki/MavenRepository处写的原始依赖项：

  <dependencies>
    <dependency>
      <groupId>com.googlecode.objectify</groupId>
      <artifactId>objectify</artifactId>
      <version>check for latest version</version>
    </dependency>
  </dependencies>

我没注意到的是文字串＆＃34;检查最新版本＆＃34;。所以我点击http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.googlecode.objectify%22然后能够看到最新版本，此时是5.1.1。

所以我把它输入到我的pom.xml中然后mvn clean install工作了：

  <dependencies>
    <dependency>
      <groupId>com.googlecode.objectify</groupId>
      <artifactId>objectify</artifactId>
      <version>5.1.1</version>
    </dependency>
  </dependencies>

构建无法解决Objectify依赖
