我正在与一个使用Eclipse的小组一起开发一个项目,但是我正在使用Netbeans.直到今天,这都不是问题.从仓库进行更新时,他们在作为/ lib-src目录下的库中添加了一些源代码.当我尝试编译代码时,出现错误,提示找不到某些软件包…这些是/ lib-src下的软件包.

使用NetBeans,我可以将库添加为文件夹,以便现在可以轻松地引用这些软件包.但是,在编译时出现了这个新错误：

/home/aaron/NetBeansProjects/xbmc-remote/nbproject/build-impl.xml:411: exec returned: 3
BUILD FAILED (total time: 1 minute 25 seconds)

如果需要,我可以包含build-impl.xml文件,但是我认为这不是主要问题.

有任何想法吗？

解决方法:

像this thread一样,是否以某种方式涉及dx.bat？

It seems that Android built tools do not use ANT_OPTS variable while running dex tool.
Problem can be solved by uncommenting line in dx.bat batch file.

You can find it in android SDK folder under platforms/YOUR_PLATFORM/tools/dx.bat.
At the very end of file there is commented command to increase heap space.
Uncommenting this line should solve the problem. Line should looks like this:

set javaOpts=-Xmx256M
