Test case failing

I checkout this project and tried to build this up using gradle. The test cases were failng. I can see that is because of some file which is missing in the directory structure. Can we check this?

Test testCommandNoDirectoryNoFile() PASSED
Test testCommandDirectoryOnly() FAILED

org.opentest4j.AssertionFailedError: expected: but was:
at rapide.iso20022.cli.MessageGeneratorCommandTest.testCommandDirectoryOnly(MessageGeneratorCommandTest.java:56)

Test testCommandDirectory_file() FAILED

org.opentest4j.AssertionFailedError: expected: but was:
at rapide.iso20022.cli.MessageGeneratorCommandTest.testCommandDirectory_file(MessageGeneratorCommandTest.java:68)

Test testCommandZipFlagWithFilePrefix() FAILED

org.opentest4j.AssertionFailedError: expected: <0> but was: <1>
at rapide.iso20022.cli.MessageGeneratorCommandTest.testCommandZipFlagWithFilePrefix(MessageGeneratorCommandTest.java:81)

Start with rapide.iso20022.cli.MessageGeneratorCommandTest.java, especially testCommandDirectoryOnly() at line 56, testCommandDirectory_file() at line 68, and testCommandZipFlagWithFilePrefix() at line 81. Reproduce the Gradle test failures and trace the missing directory or file involved; done means the three reported tests pass without breaking testCommandNoDirectoryNoFile().
