Error creating JVM using maven
提问by Deep_89
I get an error message Could not create the Java virtual machinewhen I do mvn clean install. What should I do now? Should I change anything in pom.xml? My java version-1.6 and maven version-3.0.2, all set in pom.xml
Could not create the Java virtual machine当我这样做时，我收到一条错误消息mvn clean install。我现在应该怎么办？我应该改变什么pom.xml吗？我的 java 版本 1.6 和 maven 版本 3.0.2，都设置在pom.xml
Errors are::
错误是：：

Are you using it from an IDE like Eclipse or Netbeans?
您是从 Eclipse 或 Netbeans 之类的 IDE 中使用它吗？
If so, you may then:
如果是这样，那么您可以：
- Set the JAVA_HOME to point to your JDK.
- Configure the Maven options in your IDE to use your Maven install instead of the bundled one.
- Configure the Java Runtime to use the JDK instead of the JRE.
- 将 JAVA_HOME 设置为指向您的 JDK。
- 在您的 IDE 中配置 Maven 选项以使用您的 Maven 安装而不是捆绑安装。
- 将 Java 运行时配置为使用 JDK 而不是 JRE。
Configuring the Maven installation in Eclipse
在 Eclipse 中配置 Maven 安装
- Go to Window > Preferences > Maven > Installation.
- Add your Maven installation. Click
Addand select your Maven install directory. - Select it as your Maven installation.
- 转到窗口 > 首选项 > Maven > 安装。
- 添加您的 Maven 安装。单击
Add并选择您的 Maven 安装目录。 - 选择它作为您的 Maven 安装。
Configuring the installed JREs option in Eclipse
在 Eclipse 中配置已安装的 JRE 选项
- Go to Window > Preferences > Java > Installed JREs.
- Add a Standard VM that points to your JDK home directory.
- No VM arguments. Of course, if you have any you may add them.
- Mark it as your JRE.
- 转到“窗口”>“首选项”>“Java”>“已安装的 JRE”。
- 添加一个指向 JDK 主目录的标准 VM。
- 没有 VM 参数。当然，如果你有的话，你可以添加它们。
- 将其标记为您的 JRE。
By default Eclipse uses an embedded Maven installation from the Maven plugin and sometimes uses the Non-JDK JRE as the default Java Runtime.
默认情况下，Eclipse 使用来自 Maven 插件的嵌入式 Maven 安装，有时使用非 JDK JRE 作为默认 Java 运行时。
So the steps to make it work is to have a JDK installed, set the JAVA_HOME, unpack Maven to a directory and then in Eclipse change the Maven installation and point the JRE to a JDK JRE.
因此，使其工作的步骤是安装 JDK，设置 JAVA_HOME，将 Maven 解压到一个目录，然后在 Eclipse 中更改 Maven 安装并将 JRE 指向 JDK JRE。
I hope it helps.
我希望它有帮助。

You need to find out why it could not create it. A common reason is that an invalid command line option is used. e.g. M2_OPTS=-Xmx1mwill give you this error.
您需要找出无法创建它的原因。一个常见的原因是使用了无效的命令行选项。例如M2_OPTS=-Xmx1m会给你这个错误。

Please check for the java system properties say -Xmx or -Xms which you specify in mvn clean command. I guess there might be a space between the command and the ram size. i.e you may have specified -Xmx 128rather it should be -Xmx128. It is a wild guess though
请检查您在 mvn clean 命令中指定的 java 系统属性，例如 -Xmx 或 -Xms。我猜命令和内存大小之间可能有空格。即您可能指定了 -Xmx 128而应该是-Xmx128。虽然这是一个疯狂的猜测

Also match your JAVA_HOMEenv variable with JAVA_HOME\bin in PATHenv. It should be of same arch type.
还要将您的JAVA_HOMEenv 变量与 env 中的 JAVA_HOME\bin匹配PATH。它应该是相同的拱形类型。
I faced this problem. I have 16GB ram, and even after setting set MAVEN_OPTS=-Xmx1024mit did not work after few maven executions and gave errors.
我遇到了这个问题。我有 16GB 内存，即使在设置set MAVEN_OPTS=-Xmx1024m了几次 Maven后它也不起作用并出现错误。
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
