Juniversal Translator Error：无法解析导入org.junit

Question

我正在使用Juniversal将Java转换为Objective-C和C＃

此外，JUnit已添加到Android项目（jar文件，gradle）

当我使用Mac OSX（Yosemite）终端运行命令时：

java -jar juniversal/juniversal-translator/build/libs/juniversal-translator-0.8.3.jar -o $OBJC_OUTPUT -l c# -classpath  jsimple/libraries/jsimple-util/build/libs/jsimple-util-0.9.3.jar  -sourcepath $HOME/androidstudioprojects/testbuild/app/src/main/java  $HOME/androidstudioprojects/testbuild/app/src/test/java

显示错误：
