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

Question

全。

我需要使用VSCode来制作项目。而且我也不擅长用VSCode做java项目。

我尝试用gradle的spring boot来做多项目。(Image: Project outline)

告诉我我需要做什么来解决这个问题，我会立即附上评论。

当我运行java测试时，initializationError出现如下所示：

initializationError Failed 0s

我在Scala项目中遇到了类似的问题。运行gradle build或gradle test失败得很糟糕，但是当我显式地按名称指定测试时，测试运行到完成。

测试名称为的

$ gradle test --tests xxx.MyTest

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

不带测试名称的

$ 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
    java.lang.Exception at BlockJUnit4ClassRunner.java:158

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

7 tests completed, 5 failed

> Task :test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test'.
> There were failing tests. See the report at: file:///home/xyz/build/reports/tests/test/index.html

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
