java.net.UnknownHostException: build: nodename nor servname provided, or not known

Tried simple code from the example:

Map<String, Job> jobs = null; try { jobs = jenkins.getJobs(); System.out.println(jobs.keySet()); JobWithDetails ios = jobs.get("My job").details(); } catch (IOException e) { e.printStackTrace(); }

Fails with:
java.net.UnknownHostException: build: nodename nor servname provided, or not known at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:928) at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1323) at java.net.InetAddress.getAllByName0(InetAddress.java:1276) at java.net.InetAddress.getAllByName(InetAddress.java:1192) at java.net.InetAddress.getAllByName(InetAddress.java:1126) at org.apache.http.impl.conn.SystemDefaultDnsResolver.resolve(SystemDefaultDnsResolver.java:44) at org.apache.http.impl.conn.HttpClientConnectionOperator.connect(HttpClientConnectionOperator.java:102) at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:319) at org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:363) at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:219) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:195) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:86) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:108) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:184) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at com.offbytwo.jenkins.client.JenkinsHttpClient.get(JenkinsHttpClient.java:134) at com.offbytwo.jenkins.model.Job.details(Job.java:45) at Jenkins.main(Jenkins.java:26)

Tried to google, found out several similar issues, like this. But build is not my hostname and even if I add it to /etc/hosts, this code won't run anyway.

Any idea how to fix this?

macos 10.13.1
java 1.8.0_141

Commencez par le point d’entrée de l’exemple, puis suivez Job.details dans Job.java via JenkinsHttpClient.get dans JenkinsHttpClient.java. Reproduisez la UnknownHostException avec les versions de Java et macOS indiquées et examinez où l’hôte nommé dans la requête est sélectionné. La tâche est terminée lorsque l’exemple atteint la Jenkins API sans résoudre l’hôte involontaire.
