Okay .. it seems that maven is downloading the flink-compiler artifacts from a snapshots repository:
[INFO] ------------------------------------------------------------------------ [INFO] Building flink-language-binding-generic 0.9-SNAPSHOT [INFO] ------------------------------------------------------------------------ [INFO] Downloading: https://oss.sonatype.org/content/repositories/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml [INFO] Downloading: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml [INFO] Downloading: http://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml [INFO] Downloading: https://nexus.codehaus.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml [INFO] Downloaded: http://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml (2 KB at 4.9 KB/sec) [INFO] Downloaded: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/maven-metadata.xml (2 KB at 3.0 KB/sec) [INFO] Downloading: https://oss.sonatype.org/content/repositories/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/flink-compiler-0.9-20150313.122611-190.pom [INFO] Downloading: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/flink-compiler-0.9-20150313.122611-190.pom [INFO] Downloaded: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/flink-compiler-0.9-20150313.122611-190.pom (4 KB at 6.2 KB/sec) [INFO] Downloading: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/flink-compiler-0.9-20150313.122611-190.jar [INFO] Downloaded: https://repository.apache.org/snapshots/org/apache/flink/flink-compiler/0.9-SNAPSHOT/flink-compiler-0.9-20150313.122611-190.jar (2660 KB at 2499.9 KB/sec) So maven can build because "flink-compiler:0.9-SNAPSHOT" is online available. I'm trying to see whether adding --no-snapshot-updates [1] will fail the build on travis. Once I've verified that, I'll push a fix.
