Java Jenkins-构建Vaadin Web应用程序需要很长时间

我的目标是建立一个持续的集成（intellijidea->github->jenkins->tomcat），但“构建vaadinweb应用程序”的过程不会结束（见下文）。这个过程是从我的maven构建隐式调用的，只有在我关闭服务器时才会结束（顺便说一句：服务器的ram限制为500mb）

马文在詹金斯的目标是“干净包装”。war文件将通过另一个jenkins插件部署，但jenkins甚至还没有做到这一点

我的pom的构建部分如下所示（它来自一个原型，我还没有真正理解这一部分）：

org.apache.maven.plugins
）
正如Thorbjørn指出的，问题是由于服务器的容量

第一个服务器ram限制为512 mb，没有交换空间（主机最初不提供交换）。增加交换空间会导致相同的结果。因此，我选择了另一台具有1GB ram且无交换的服务器。在这种情况下，我遇到了一个“状态137的maven失败”，它告诉我（通过谷歌）使用swap

这就做到了：至少1 gb内存和一些交换（在我的例子中是4 gb）。vaadin widgetsets的汇编似乎相当繁重。
它很可能会变成死亡。您的JVM选项没有针对您的虚拟机进行调整。6年后，情况仍然如此！
