I have logback/trunk checked out, and did a "svn update; mvn clean; mvn compile; mvn install" to get up to speed. The "mvn install" hangs - apparently in a test - with this being the last printed: Running ch.qos.logback.classic.net.SMTPAppender_SubethaSMTPTest [HEADER 11469 [main] DEBUG test ch.qos.logback.classic.net.SMTPAppender_SubethaSMTPTest - hello 11469 [main] ERROR test ch.qos.logback.classic.net.SMTPAppender_SubethaSMTPTest - en error java.lang.Exception: an exception at ch.qos.logback.classic.net.SMTPAppender_SubethaSMTPTest.smoke(SMTPAppender_SubethaSMTPTest.java:121) [test-classes/:na] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [na:1.5.0] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) [na:1.5.0] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [na:1.5.0] at java.lang.reflect.Method.invoke(Method.java:585) [na:1.5.0] at org.junit.internal.runners.TestMethod.invoke(TestMethod.java:59) [junit-4.4.jar:na] at org.junit.internal.runners.MethodRoadie.runTestMethod(MethodRoadie.java:98) [junit-4.4.jar:na] at org.junit.internal.runners.MethodRoadie$2.run(MethodRoadie.java:79) [junit-4.4.jar:na] at org.junit.internal.runners.MethodRoadie.runBeforesThenTestThenAfters(MethodRoadie.java:87) [junit-4.4.jar:na] at org.junit.internal.runners.MethodRoadie.runTest(MethodRoadie.java:77) [junit-4.4.jar:na] at org.junit.internal.runners.MethodRoadie.run(MethodRoadie.java:42) [junit-4.4.jar:na] at org.junit.internal.runners.JUnit4ClassRunner.invokeTestMethod(JUnit4ClassRunner.java:88) [junit-4.4.jar:na] at org.junit.internal.runners.JUnit4ClassRunner.runMethods(JUnit4ClassRunner.java:51) [junit-4.4.jar:na] at org.junit.internal.runners.JUnit4ClassRunner$1.run(JUnit4ClassRunner.java:44) [junit-4.4.jar:na] at org.junit.internal.runners.ClassRoadie.runUnprotected(ClassRoadie.java:27) [junit-4.4.jar:na] at org.junit.internal.runners.ClassRoadie.runProtected(ClassRoadie.java:37) [junit-4.4.jar:na] at org.junit.internal.runners.JUnit4ClassRunner.run(JUnit4ClassRunner.java:42) [junit-4.4.jar:na] at org.apache.maven.surefire.junit4.JUnit4TestSet.execute(JUnit4TestSet.java:62) [surefire-junit4-2.4.2.jar:2.4.2] at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.executeTestSet(AbstractDirectoryTestSuite.java:140) [surefire-api-2.4.2.jar:2.1] at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.execute(AbstractDirectoryTestSuite.java:127) [surefire-api-2.4.2.jar:2.1] at org.apache.maven.surefire.Surefire.run(Surefire.java:177) [surefire-api-2.4.2.jar:2.1] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [na:1.5.0] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) [na:1.5.0] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [na:1.5.0] at java.lang.reflect.Method.invoke(Method.java:585) [na:1.5.0] at org.apache.maven.surefire.booter.SurefireBooter.runSuitesInProcess(SurefireBooter.java:338) [surefire-booter-2.4.2.jar:na] at org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:997) [surefire-booter-2.4.2.jar:na] FOOTER Before digging in, is there a step I have missed? -- Thorbjørn Ravn Andersen "...plus...
