如何从 Spring 引导应用程序中的 Gradle 测试收集堆转储？

Question

我在 Spring 启动应用程序中运行集成测试时试图诊断 memory 泄漏。

当我跑步时：

./gradlew test -i --XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/Users/ng.newbie/Desktop/heapdump.bin

我不断收到 OOM 错误：

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pem.item.service.exchange.allocation-97"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pem.item.service.exchange.itemAssortment-97"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pem.item.service.exchange.order-97"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pem.item.service.exchange.planning-97"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "HikariPool-37 housekeeper"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "HikariPool-1 housekeeper"

但是指定目录中没有堆转储。

我还尝试将以下内容添加到我的gradle.properties ：

org.gradle.jvmargs=-XX:MaxPermSize=512m -XX:PermSize=128m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/Users/ng.newbie/Desktop/crash.hprof

没变。

我究竟做错了什么？
