Neo4j社区版安装问题HostnamePortTest失败

Question

我尝试安装了两个版本的Neo4j社区版(4.2.0-快照和4.1.4-快照)。这两种方法都失败了，并出现以下错误：

[ERROR] Failures: 
[ERROR]   HostnamePortTest.testGetHostAddressUnknown:121 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR]   HostnamePortTest.testMatchesIPWithHostUnknown:267 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR]   HostnamePortTest.testMatchesKnownHostWithHostUnknown:332 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR]   HostnamePortTest.testMatchesNullHostWithUnknownHost:387 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[ERROR]   HostnamePortTest.testMatchesUnknownHosts:135 Expected java.net.UnknownHostException to be thrown, but nothing was thrown.
[INFO] 
[ERROR] Tests run: 222, Failures: 5, Errors: 0, Skipped: 0

我可以在启用跳过测试标志的情况下完成安装，但稍后当我尝试连接到Neo4j时，我会收到以下错误：

[error] Oct 08, 2020 10:50:19 AM org.neo4j.driver.internal.logging.JULogger info
[error] INFO: Direct driver instance 1881901842 created for server address localhost:7687
[error] Oct 08, 2020 10:50:19 AM org.neo4j.driver.internal.logging.JULogger info

[error] Oct 08, 2020 10:50:19 AM org.neo4j.driver.internal.logging.JULogger info
[error] INFO: Closing connection pool towards localhost:7687

有人能帮帮忙吗?我不确定这些错误是怎么回事？谢谢,

尽管测试用例会产生错误，但看起来Neo4j社区版工作得很好。我仍然不确定这些错误是从哪里来的，它们没有太大的意义。至于第二部分，看起来Neo4j Java driver正在将INFO消息作为错误消息打印到控制台(错误信息:正在关闭驱动程序实例1496355635)。再一次，我不确定为什么。我的解决方案是在安装过程中使用以下命令跳过测试用例: mvn install -DskipTests
