如何从 Spring 引导应用程序中的 Gradle 测试收集堆转储？

Question

我在运行我的 Spring 启动应用程序中进行集成测试时试图诊断内存泄漏。

当我运行 :

./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

没有变化。

我做错了什么？
