在尝试创建dex时,android-maven-plugin会导致java.lang.OutOfMemoryError

概述我需要一只手.我在 android项目中使用 android-maven-plugin 3.0.0和maven-external-dependency-plugin 0.4.我正在使用来自不同存储库的这些库作为依赖项： <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit 我需要一只手.我在 android项目中使用 android-maven-plugin 3.0.0和maven-external-dependency-plugin 0.4.我正在使用来自不同存储库的这些库作为依赖项：

依赖性都很满意,但是当把所有的罐子都装入AndroID dex的时候,我得到一个内存不足的错误：

[INFO] UNEXPECTED top-LEVEL ERROR:[INFO] java.lang.OutOfMemoryError: Java heap space[INFO]  at com.androID.dx.cf.code.OneLocalsArray.<init>(OneLocalsArray.java:46)[INFO]  at com.androID.dx.cf.code.OneLocalsArray.copy(OneLocalsArray.java:51)[INFO]  at com.androID.dx.cf.code.OneLocalsArray.copy(OneLocalsArray.java:33)[INFO]  at com.androID.dx.cf.code.Frame.copy(Frame.java:98)[INFO]  at com.androID.dx.cf.code.Ropper.processBlock(Ropper.java:683)[INFO]  at com.androID.dx.cf.code.Ropper.doit(Ropper.java:639)[INFO]  at com.androID.dx.cf.code.Ropper.convert(Ropper.java:252)[INFO]  at com.androID.dx.dex.cf.CfTranslator.processMethods(CfTranslator.java:256)[INFO]  at com.androID.dx.dex.cf.CfTranslator.translate0(CfTranslator.java:134)[INFO]  at com.androID.dx.dex.cf.CfTranslator.translate(CfTranslator.java:87)[INFO]  at com.androID.dx.command.dexer.Main.processClass(Main.java:483)[INFO]  at com.androID.dx.command.dexer.Main.processfileBytes(Main.java:455)[INFO]  at com.androID.dx.command.dexer.Main.access0(Main.java:67)[INFO]  at com.androID.dx.command.dexer.Main.processfileBytes(Main.java:394)[INFO]  at com.androID.dx.cf.direct.ClasspathOpener.processArchive(ClasspathOpener.java:245)[INFO]  at com.androID.dx.cf.direct.ClasspathOpener.processOne(ClasspathOpener.java:131)[INFO]  at com.androID.dx.cf.direct.ClasspathOpener.process(ClasspathOpener.java:109)[INFO]  at com.androID.dx.command.dexer.Main.processOne(Main.java:418)[INFO]  at com.androID.dx.command.dexer.Main.processAllfiles(Main.java:329)[INFO]  at com.androID.dx.command.dexer.Main.run(Main.java:206)[INFO]  at com.androID.dx.command.dexer.Main.main(Main.java:174)[INFO]  at com.androID.dx.command.Main.main(Main.java:95)

试图增加内存添加这个：

<plugin>    <groupID>org.apache.maven.plugins</groupID>    <artifactID>maven-surefire-plugin</artifactID>    <configuration>        <forkMode>pertest</forkMode>        <argline>-xms1024m -Xmx2048m</argline>        <testFailureIgnore>false</testFailureIgnore>        <skip>false</skip>    </configuration></plugin>

或这个：

<plugin>    <groupID>com.jayway.maven.plugins.androID.generation2</groupID>    <artifactID>androID-maven-plugin</artifactID>    <inherited>true</inherited>    <configuration>        <argline>-Xmx1024m</argline>

…

或者像这样导出maven_opts：

export MAVEN_OPTS=-Xmx1024m

不解决问题

我收到几个警告,关于使用旧类格式编译的依赖文件中的类,但我不确定这是问题的根源：

[INFO] warning: Ignoring InnerClasses attribute for an anonymous inner class[INFO] (org.osgi.framework.adminPermission) that doesn't come with an[INFO] associated EnclosingMethod attribute. This class was probably produced by a[INFO] compiler that dID not target the modern .class file format. The recommended[INFO] solution is to recompile the class from source,using an up-to-date compiler[INFO] and without specifying any "-target" type options. The consequence of ignoring[INFO] this warning is that reflective operations on this class will incorrectly[INFO] indicate that it is *not* an inner class.

我将不胜感激任何帮助.这是从控制台打开调试的完整输出,因此您可以仔细查看错误：

最好.

达马

解决方法 这是一个已知的问题,但我相信它已在androID-maven-plugin 3.1.0中得到修复.最新的是3.1.1.你没有发布你的pom.xml,所以我不知道这是不是问题,但听起来就是这样.

如果由于某种原因无法升级,则这是适用的配置：

<dex>    <jvmArguments>      <jvmArgument>-xms256m</jvmArgument>      <jvmArgument>-Xmx512m</jvmArgument>    </jvmArguments>       </dex>

这是他们网站上报道的问题：http://code.google.com/p/maven-android-plugin/issues/detail?id=146

还有Springsource博客：http://blog.springsource.org/2011/11/07/updated-maven-support-for-android-projects/
