在Intellij-idea中用maven编译项目时出现了下面的异常信息：

系统资源不足。有关详细信息，请参阅以下堆栈追踪。java.lang.OutOfMemoryError: Java heap spaceat com.sun.tools.javac.zip.ZipFileIndex$ZipDirectory.findCENRecord(ZipFileIndex.java:698)at com.sun.tools.javac.zip.ZipFileIndex$ZipDirectory.<init>(ZipFileIndex.java:665)at com.sun.tools.javac.zip.ZipFileIndex.checkIndex(ZipFileIndex.java:260)at com.sun.tools.javac.zip.ZipFileIndex.<init>(ZipFileIndex.java:209)at com.sun.tools.javac.zip.ZipFileIndex.getZipFileIndex(ZipFileIndex.java:115)at com.sun.tools.javac.util.DefaultFileManager.openArchive(DefaultFileManager.java:636)at com.sun.tools.javac.util.DefaultFileManager.listDirectory(DefaultFileManager.java:325)at com.sun.tools.javac.util.DefaultFileManager.list(DefaultFileManager.java:872)at com.sun.tools.javac.jvm.ClassReader.fillIn(ClassReader.java:2130)at com.sun.tools.javac.jvm.ClassReader.complete(ClassReader.java:1781)at com.sun.tools.javac.code.Symbol.complete(Symbol.java:386)at com.sun.tools.javac.comp.Enter.visitTopLevel(Enter.java:272)at com.sun.tools.javac.tree.JCTree$JCCompilationUnit.accept(JCTree.java:446)at com.sun.tools.javac.comp.Enter.classEnter(Enter.java:236)at com.sun.tools.javac.comp.Enter.classEnter(Enter.java:250)at com.sun.tools.javac.comp.Enter.complete(Enter.java:444)at com.sun.tools.javac.comp.Enter.main(Enter.java:429)at com.sun.tools.javac.main.JavaCompiler.enterTrees(JavaCompiler.java:819)at com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:727)at com.sun.tools.javac.main.Main.compile(Main.java:353)at com.sun.tools.javac.main.Main.compile(Main.java:279)at com.sun.tools.javac.main.Main.compile(Main.java:270)at com.sun.tools.javac.Main.compile(Main.java:87)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)at java.lang.reflect.Method.invoke(Method.java:597)at org.codehaus.plexus.compiler.javac.JavacCompiler.compileInProcess(JavacCompiler.java:554)at org.codehaus.plexus.compiler.javac.JavacCompiler.compile(JavacCompiler.java:161)at org.apache.maven.plugin.AbstractCompilerMojo.execute(AbstractCompilerMojo.java:605)at org.apache.maven.plugin.CompilerMojo.execute(CompilerMojo.java:128)at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:490)[INFO] 1error[INFO] -------------------------------------------------------------[INFO] ------------------------------------------------------------------------[ERROR] BUILD FAILURE[INFO] ------------------------------------------------------------------------[INFO] Compilation failureFailure executing javac, but could not parse the error:系统资源不足。有关详细信息，请参阅以下堆栈追踪。java.lang.OutOfMemoryError: Java heap spaceat com.sun.tools.javac.zip.ZipFileIndex$ZipDirectory.findCENRecord(ZipFileIndex.java:698)at com.sun.tools.javac.zip.ZipFileIndex$ZipDirectory.<init>(ZipFileIndex.java:665)at com.sun.tools.javac.zip.ZipFileIndex.checkIndex(ZipFileIndex.java:260)at com.sun.tools.javac.zip.ZipFileIndex.<init>(ZipFileIndex.java:209)at com.sun.tools.javac.zip.ZipFileIndex.getZipFileIndex(ZipFileIndex.java:115)at com.sun.tools.javac.util.DefaultFileManager.openArchive(DefaultFileManager.java:636)at com.sun.tools.javac.util.DefaultFileManager.listDirectory(DefaultFileManager.java:325)at com.sun.tools.javac.util.DefaultFileManager.list(DefaultFileManager.java:872)at com.sun.tools.javac.jvm.ClassReader.fillIn(ClassReader.java:2130)at com.sun.tools.javac.jvm.ClassReader.complete(ClassReader.java:1781)at com.sun.tools.javac.code.Symbol.complete(Symbol.java:386)at com.sun.tools.javac.comp.Enter.visitTopLevel(Enter.java:272)at com.sun.tools.javac.tree.JCTree$JCCompilationUnit.accept(JCTree.java:446)at com.sun.tools.javac.comp.Enter.classEnter(Enter.java:236)at com.sun.tools.javac.comp.Enter.classEnter(Enter.java:250)at com.sun.tools.javac.comp.Enter.complete(Enter.java:444)at com.sun.tools.javac.comp.Enter.main(Enter.java:429)at com.sun.tools.javac.main.JavaCompiler.enterTrees(JavaCompiler.java:819)at com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:727)at com.sun.tools.javac.main.Main.compile(Main.java:353)at com.sun.tools.javac.main.Main.compile(Main.java:279)at com.sun.tools.javac.main.Main.compile(Main.java:270)at com.sun.tools.javac.Main.compile(Main.java:87)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)at java.lang.reflect.Method.invoke(Method.java:597)at org.codehaus.plexus.compiler.javac.JavacCompiler.compileInProcess(JavacCompiler.java:554)at org.codehaus.plexus.compiler.javac.JavacCompiler.compile(JavacCompiler.java:161)

四个字就是：内存溢出了，出现这个问题，首先我们第一印象是maven内存不够用了，于是修改maven的bat文件，修改它的内存，但是修改后没有效果。然后我们会继续修改intellij-idea的内存，但是都没有效果。

为什么呢？因为我们没有找对点，我们应该修改pom.xml文件中编译插件的内存设置，如下：

<project>  [...]  <build>    [...]    <plugins>      <plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-compiler-plugin</artifactId>        <version>3.1</version>        <configuration>          <fork>true</fork>          <meminitial>512m</meminitial>          <maxmem>1048m</maxmem>        </configuration>      </plugin>    </plugins>    [...]  </build>  [...]</project>

你需要根据你的实际情况修改maven-compiler-plugin的内存配置。
