java虚拟机崩溃

Question

我编写了一个 Java Spring-WS-Application 服务器并尝试使用 maven 从命令行部署它。但是，当尝试执行“mvn clean package”时，它告诉我由于堆空间不足而无法创建 Java 虚拟机。我的电脑只有 4GB 的 RAM，而且运行的是 32 位 Windows。只要我包含 -DskipTests，部署就会成功。

这个项目依赖于我的团队编写的其他项目，我可以使用“mvn clean install”毫无问题地部署它们。我也可以毫无问题地部署其他服务器，所以我认为我的 java 版本没有损坏。此外，我的开发团队的其他成员已经能够在他们的机器上成功部署此服务器。

我还检查并注释掉了所有 @Test 注释以尝试查找错误测试，但是当没有要运行的测试时它仍然给我这个错误。

对于为什么会发生这种情况有什么想法吗？

Java 版本：

java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) Client VM (build 23.21-b01, mixed mode, sharing)

“mvn clean package:”的结果

Answer 1

仔细查看错误消息。它说没有足够的内存用于测试 JVM 的堆。尝试释放一些内存（关闭 Eclipse）和/或使用较低的堆/永久生成大小运行测试（确保设置）。
