Hi,
I am seeing a periodic error when running our builds on Windows. When running "mvn clean verify" I occasionally see errors like the following: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:testCompile (test-compile) on project single-application-test: Fatal error compiling: directory not found: C:\projects\myproject\system-test\tests-v2\singleApplicationTest\target\test-classes -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException [ERROR] [ERROR] After correcting the problems, you can resume the build with the command [ERROR] mvn <goals> -rf :single-application-test If I immediately rerun the same "mvn clean verify" command, it works. Has anyone else seen such problems? Thanks, Robert
