从Nexus 2.14升级到Nexus 3.x（3.4.0-02）后，
当我们运行deploy：deploy时，我们现在从Maven作业中获得500个错误
Failed to transfer file: https://nexus.foo.net/repository/snapshots/com/foo/foo-server/1.1.0-SNAPSHOT/maven-metadata.xml. Return code is: 500 , ReasonPhrase:javax.servlet.ServletException: com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: sql.select from asset where bucket = :bucket and name = :propValue?? DB name="component".
除了作为显示基础数据库查询的安全漏洞之外，错误对于我们排除故障是非常不透明的。有谁见过这个？
后端nexus日志具有此堆栈跟踪。基本上看起来像NPE。

可能是你遗漏了下面讨论过的几件事，或者你错误地写了这个查询： 请检查您是否已将正确的URL写入服务器，或者您无法访问服务器或特定目标存储库，或者您还没有正确编写SQL查询。

我到底了。首次安装Nexus 3时，它会显示已配置的内存使用量低于实际可用内存的消息。
这促使我调低nexus.vmoptions并重启服务。
最终通过一系列的故障排除，我意识到东方数据库没有足够的“直接内存”。分配。基本上没有新的blob商店，没有新设置，也没有上传可能。
我恢复了默认的nexus.vmoptions，并且它再次正常运行。提示原始更改的内存消息实际上记录为＆＃34; WARN＆＃34;如果仔细观察这极具误导性。
我还会调用Nexus左右抛出NullPointerExceptions而不是简单地指出内存不足问题是一个缺陷。希望Sonatype的某人能够读到这一点，因为它耗费了4个小时来解决这个问题。
