TomEE 启动错误：无法创建唯一文件，请将 java.io.tmpdir 设置为可写文件夹或创建工作文件夹

Question

从 IntelliJ 14 中启动我的应用程序时，应用服务器 TomEE 7.0.62 提供以下错误消息：

cannot create unique file, please set java.io.tmpdir to a writable folder or create work folder
at org.apache.openejb.assembler.DeployerEjb.<clinit>(DeployerEjb.java:109)

系统： OSX、IntelliJ 14、TomEE-Plume 7.0.62（自制）、Java 8（自制桶）

Java 版本：

/usr/libexec/java_home -V
Matching Java Virtual Machines (1):
1.8.0_60, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

部署：来自 Vaadin Framework 7 的基本 Hello World 示例应用

信息：

• 在终端上使用 startup.sh 启动 TomEE 可以正常工作，默认的 tomcat 欢迎屏幕显示在 localhost:8080
• 尝试添加 JVM 选项以将 java.io.tmpdir 设置为具有 chmod 777 权限的不同目录。 VM options: -Djava.io.tmpdir=<new temp dir>
• 尝试使用export _JAVA_OPTIONS=-Djava.io.tmpdir=<new temp dir> 导出环境变量
• 使用 Tomcat 8 hello world 应用可以正常工作

您可以在 conf/system.properties 中添加 openejb.system.apps=false 或将 CATALINA_TMPDIR 导出到“新的 tmp dir 值”
