当 运行 Liquibase 插件在 Gradle 时，“java.lang.ArrayIndexOutOfBoundsException: 0”是什么意思？
What does " java.lang.ArrayIndexOutOfBoundsException: 0" mean when running Liquibase plugin in Gradle?
我在 Windows 7 上使用 Gradle 2.7（在 cygwin 中为 bash shell）。我想在 testClasses 阶段之前执行我的 LIquibase 插件的更新任务，所以我有
liquibase {
activities {
main {
File propsFile = new File("${project.rootDir}/src/main/resources/liquibase.properties")
Properties properties = new Properties()
properties.load(new FileInputStream(propsFile))
changeLogFile 'src/main/resources/db.changelog-1.0.xmlll'
url '${url}'
username '${username}'
password '${password}'
}
runList = main
}
}
testClasses.dependsOn update
但是，当我 运行 "gradle build --stacktrace" 时，出现以下错误。这是什么意思，或者我怎样才能获得更多信息来弄清楚发生了什么？

runList 应指定为字符串（注意 main 周围的引号）

我运行遇到了同样的问题。 JUnit 测试通过了我的 IDE，但在 Maven 构建中失败了。
从
切换
@RunWith(MockitoJUnitRunner.class)

@RunWith(PowerMockRunner.class)
