Maven 无法组装 WAR - Java 堆空间问题 - Stanford Core NLP

Question

所以我在尝试使用 Maven 进行全新安装时遇到此错误。我尝试使用 Xmx-512m 增加 MAVEN_OPTS 或 w/e 它被调用，类似地摆弄 Eclipse ini 以增加堆空间，但所有这些都无济于事，我不断收到此错误：

我不明白是什么原因造成的，试图在网上查找信息，但似乎找不到其他人遇到的这个具体问题。如果有人能提供帮助，我将不胜感激。

Answer 1

刚刚想通了，

首先，我错误地设置了 MAVEN_OPTS，我将它们设置为：

set MAVEN_OPTS="Xmx 512m"

将其更改为：

set MAVEN_OPTS="-Xmx512m"

您还可以将此行添加到您的配置文件（.profile、.bash_profile 等）中，以便在您打开的每个终端中进行设置。

export MAVEN_OPTS="-Xmx512m"

然后使用CMD进入项目所在的目录， 我跑了：

mvn clean install -U

这似乎成功了，一切顺利。

希望这可以帮助其他遇到问题的人！

Answer 2

我在 Windows 机器上通过 Jenkins 的 ant 运行 maven 时遇到了同样的问题。

问题是如何传递内存参数。这是更新后的 ant 脚本，展示了如何传递参数“<jvmarg value="-Xmx1024m" />”：

<target name="web.package" depends="init" if="warName">
    <artifact:mvn mavenHome="${maven.home}" failonerror="true" fork="true">
        <jvmarg value="-Dmaven.multiModuleProjectDirectory=$M2_HOME" />
        <jvmarg value="-Xmx1024m" />
        <arg value="package" />
        <arg value="-Pwar" />
        <arg value="-DwarName=${warName}" />
        <arg value="-Denv=${env}" />
        <arg value="-e" />
    </artifact:mvn>
</target>

有关信息，这里是崩溃输出：
