我尝试将cn1lib集成到Native Data Transfer，它可以在Extensions-Page上找到。不幸的是，当集成这个lib时，会出现一些构建错误：缺少一些awt类（例如import java.awt.Component;）。
我不知道，为了完成构建，究竟缺少什么。
以下是带有构建错误的完整控制台输出：

答案 0 :(得分：1)
当前版本的Eclipse build.xml模板中似乎存在错误。我已经应用了一个将在下一个插件更新中包含的修复程序。与此同时，您需要对build.xml文件进行一些小改动。
在build.xml的第170行附近，有一个javac调用：
<javac destdir="native/internal_tmp" compiler="modern"
source="1.8"
target="1.8"
bootclasspath="lib/CLDC11.jar"
classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp">
<src path="native/javase"/>
<src path="lib/impl/native/javase"/>
</javac>
删除bootclasspath=行，最后得到：
<javac destdir="native/internal_tmp" compiler="modern"
source="1.8"
target="1.8"
classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp">
<src path="native/javase"/>
<src path="lib/impl/native/javase"/>
</javac>
