java - VSCode, Spring boot, Gradle, Make Multi-Project, 如何解决initializationError？

问题描述

全部。
我需要使用 VSCode 来制作项目。而且我不擅长用 VSCode 制作 java 项目。
我尝试使用带有 gradle 的 spring boot 来制作多项目。（图片：项目大纲）
告诉我我需要做什么来解决问题，我会立即附上评论。
当我运行 java 测试时，initializationError 发生如下：

initializationError Failed 0s

解决方案

我有一个类似的问题，但有一个 Scala 项目。运行gradle build或gradle test失败很惨，但是当我按名称明确指定测试时，测试运行完成。

带有测试名称

$ gradle test --tests xxx.MyTest

BUILD SUCCESSFUL in 13s
3 actionable tasks: 1 executed, 2 up-to-date

没有测试名称

$ gradle test 

> Task :test

xxx.UnitSpec > initializationError FAILED
    java.lang.Exception at BlockJUnit4ClassRunner.java:191

xxx.SparkSessionTestWrapper > initializationError FAILED
    java.lang.Exception at BlockJUnit4ClassRunner.java:158

xxx.SparkSessionTestWrapper > initializationError FAILED
    java.lang.Exception at BlockJUnit4ClassRunner.java:191

xxx.SparkSessionTestWrapper$class > initializationError FAILED

xxx.SparkSessionTestWrapper$class > initializationError FAILED
    java.lang.Exception at BlockJUnit4ClassRunner.java:191

7 tests completed, 5 failed

> Task :test FAILED
