在 Jenkins 中为 Java Ant 任务构建失败

Question

我在 Amazon t2.micro Ubuntu 实例中的 Jenkins 中运行 ant。Java 任务失败。下面是我的 Jenkins 控制台

 [java] Compiling module com.eit.manufacturing.displayprocessor.Manufacturing
 [java] Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000ed84e000, 53288960, 0) failed; error='Cannot allocate memory' (errno=12)
 [java] #
 [java] # There is insufficient memory for the Java Runtime Environment to continue.
 [java] # Native memory allocation (malloc) failed to allocate 53288960 bytes for committing reserved memory.
 [java] # An error report file with more information is saved as:
 [java] # /root/.jenkins/jobs/Manufacturing Apps/workspace/ManufacturingWeb/hs_err_pid5235.log

这是我的蚂蚁脚本：

<target
    name="clientcompile"
    depends="servercompile"
    description="GWT compile to JavaScript (production mode)" >
    <java
        classname="com.google.gwt.dev.Compiler"
        failonerror="true"
        fork="true" >
        <classpath>
        <pathelement location="src" />
        <path refid="project.class.path" />
        <pathelement location="${gwt.sdk}validation-api-1.0.0.GA.jar" />
        <pathelement location="${gwt.sdk}validation-api-1.0.0.GA-sources.jar" />
        </classpath>
        <jvmarg value="-Xmx256M" />
        <arg line="-war" />
        <arg value="war" />
        <arg line="${gwt.args}" />
        <arg value="com.eit.manufacturing.displayprocessor.Manufacturing" />
   </java>
</target>

如何解决这个问题？
