我有一些简单的扩展和一些测试。当我通过intellij运行测试时，它们工作正常。
作为尝试使用命令行工作的一部分，我尝试了./gradlew build，但现在测试失败，我不确定如何继续。
扩展名：
package com.example
fun <T> ArrayList<T>.join(separator: String): String {
return StringUtils.join(this.map {it.toString()}, separator)
}
fun <T> List<T>.join(separator: String): String {
return StringUtils.join(this.map {it.toString()}, separator)
}
测试：
import com.example.join
import org.junit.Assert.assertEquals
import org.junit.Test
class TestArrayList {
@Test fun joinsToString() {
val container = arrayListOf('A', 'B', 'C')
assertEquals("ABC", container.join("")) // line 9
assertEquals("A -> B -> C", container.join(" -> "))
}
}
class TestList {
@Test fun joinsToString() {
val container = listOf('A', 'B', 'C')
assertEquals("ABC", container.join("")) // line 19
assertEquals("A -> B -> C", container.join(" -> "))
}
}
