我试图在apache的Maven项目上运行evosuite，但出现的错误主要是：
* Error while initializing target class: java.lang.NullPointerException
要引起此错误，这是我正在运行的命令：
mvn dependency:copy-dependencies
mvn dependency:unpack-dependencies
java -jar "C:\Program Files\Evosuite\evosuite-1.0.6.jar" -projectCP tika-parsers\target\classes;tika-parsers\target\dependency -class org.apache.tika.parser.iwork.KeynoteContentHandler -Dassertion_strategy=ALL -criterion BRANCH:EXCEPTION:METHOD -Dtest_dir=C:\Users\amirelm\Code\rotem\BugMiner\ignore_me\projects\tika\.evosuite\best-tests
产生的错误是：
* EvoSuite 1.0.6
* Going to generate test cases for class: org.apache.tika.parser.iwork.KeynoteContentHandler
* Starting client
* Connecting to master process on port 10483
* Analyzing classpath:
- tika-parsers\target\classes
- tika-parsers\target\dependency
* Error while initializing target class: java.lang.NullPointerException

有人知道要解决吗？
