我正在尝试使用提供的示例，但是当我添加另一个用POJO创建的jar时，我无法再编译应用程序
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>maven-android-plugin</artifactId>
<version>2.8.4</version>
<configuration>
<sdk>
<platform>9</platform>
</sdk>
<emulator>
<avd>23</avd>
<wait>10000</wait>
<!--<options>-no-skin</options>-->
</emulator>
<zipalign>
<verbose>true</verbose>
</zipalign>
<deleteConflictingFiles>true</deleteConflictingFiles>
<undeployBeforeDeploy>true</undeployBeforeDeploy>
</configuration>
</plugin>
当我使用我创建的jar时，我收到此OOM错误
[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.

我甚至试过提高内存
set JAVA_OPTS="%JAVA_OPTS% -Xmx512m -XX:MaxPermSize=768m"
但由于某种原因仍然用完了。
现在，当我尝试使用其他人的另一个jar时，请说Crest声称它可以与Android开箱即用：
<dependency>
<groupId>org.codegist.crest</groupId>
<artifactId>codegist-crest</artifactId>
</dependency>
然后我尝试构建并得到此错误：
[INFO] trouble processing "javax/xml/bind/annotation/adapters/CollapsedStringAdapter.class":
[INFO]
[INFO] Ill-advised or mistaken usage of a core class (java.* or javax.*)
[INFO] when not building a core library.
[INFO]
...
[INFO] If you are legitimately using some code that happens to be in a
[INFO] core package, then the easiest safe alternative you have is to
[INFO] repackage that code. That is, move the classes in question into
[INFO] your own package namespace. This means that they will never be in
[INFO] conflict with core system classes. JarJar is a tool that may help
[INFO] you in this endeavor. If you find that you cannot do this, then
[INFO] that is an indication that the path you are on will ultimately
[INFO] lead to pain, suffering, grief, and lamentation.
所以
如何确定我可以在Android应用程序中使用哪些类？
如何构建
答案 0 :(得分：2)
关于OOM： 尝试设置MAVEN_OPTS =“ - Xmx512m”而不是JAVA_OPTS
关于核心课程：您获得的信息非常丰富。你包含的jar包含核心命名空间中的一些类，这是不允许的。您可以按照建议使用jarjar。
