Halil İbrahim Şener updated SUREFIRE-2051: ------------------------------------------ Description: We see {{NullPointerException}} s from time to time, similar to https://issues.apache.org/jira/browse/SUREFIRE-1837 and https://issues.apache.org/jira/browse/SUREFIRE-1928. Relevant stack traces: {code} Caused by: java.lang.NullPointerException: Cannot invoke "java.io.File.getAbsolutePath()" because the return value of "org.apache.maven.artifact.Artifact.getFile()" is null at org.apache.maven.plugin.surefire.SurefireDependencyResolver.getProviderClasspath (SurefireDependencyResolver.java:218) at org.apache.maven.plugin.surefire.SurefireDependencyResolver.getProviderClasspathAsMap (SurefireDependencyResolver.java:230) at org.apache.maven.plugin.surefire.AbstractSurefireMojo$JUnitPlatformProviderInfo.getProviderClasspath (AbstractSurefireMojo.java:3215) at org.apache.maven.plugin.surefire.AbstractSurefireMojo.newStartupConfigWithClasspath (AbstractSurefireMojo.java:1908) at org.apache.maven.plugin.surefire.AbstractSurefireMojo.createStartupConfiguration (AbstractSurefireMojo.java:1894) {code} and when debug is enabled: {code} Caused by: java.lang.NullPointerException: Cannot invoke "java.io.File.getAbsolutePath()" because the return value of "org.apache.maven.artifact.Artifact.getFile()" is null at org.apache.maven.plugin.surefire.AbstractSurefireMojo$ClasspathCache.setCachedClasspath (AbstractSurefireMojo.java:4121) at org.apache.maven.plugin.surefire.AbstractSurefireMojo$ClasspathCache.access$200 (AbstractSurefireMojo.java:4102) at org.apache.maven.plugin.surefire.AbstractSurefireMojo.newStartupConfigWithClasspath (AbstractSurefireMojo.java:1913) at org.apache.maven.plugin.surefire.AbstractSurefireMojo.createStartupConfiguration (AbstractSurefireMojo.java:1894) {code} Mentioned tickets point to https://github.com/apache/maven/pull/627. However, we had already upgraded to Maven 3.8.5 and it was still happening. After digging the Surefire code, I realized NPE is a red herring because Surefire doesn't propagate the issue during artifact resolution, and then later, it fails with NPE. In our case, the remote repository wasn't reliable, e.g., it sometimes returns 500. I think Surefire should propagate the actual artifact resolution issue instead. Similar to Maven compiler plugin https://github.com/apache/maven-compiler-plugin/blob/785089d48541899b5c0a4677942b0f66c2f71d39/src/main/java/org/apache/maven/plugin/compiler/AbstractCompilerMojo.java#L1838 was: We see {{NullPointerException}}s from time to time, similar to https://issues.apache.org/jira/browse/SUREFIRE-1837 and https://issues.apache.org/jira/browse/SUREFIRE-1928.
