Liu, Linhong updated SPARK-26299: --------------------------------- Description: In spark root pom, there is a test-jar execution for all sub-projects including spark-streaming. This will attach an artifact: org.apache.spark:spark-streaming_2.11:*{color:#ff0000}test-jar{color}*:tests:2.3.2 Also, in streaming pom, there is a shade test configuration, it will attach an artifact: org.apache.spark:spark-streaming_2.11:{color:#ff0000}*jar*{color}:tests:2.3.2 But two artifacts actually point to the same file: spark-streaming_2.11-2.3.2-tests.jar So, when deploy spark to nexus using mvn deploy, maven will upload the test.jar twice since it belongs to 2 artifacts. Then deploy fails due to nexus don't allow overrides existing file for non-SNAPSHOT release. What's more, after checking the spark-streaming, shaded test jar is exactly same to original test jar. It seems we can just delete the related shade config. {code:java} <build> <outputDirectory>target/scala-${scala.binary.version}/classes</outputDirectory> <testOutputDirectory>target/scala-${scala.binary.version}/test-classes</testOutputDirectory> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <configuration> <shadeTestJar>true</shadeTestJar> </configuration> </plugin> </plugins> </build>{code} was: In spark root pom, there is a test-jar execution for all sub-projects including spark-streaming.
