我正在尝试在我的 Android 项目中使用Natty NLP 库。
我已经使用 Maven 在 IntelliJ 中建立了新的 hello world 项目（如本文所述；刚刚下载了模板）并添加了 Natty 作为依赖项。
public void onCreate(Bundle savedInstanceState)
{
Parser parser = new Parser();
List<DateGroup> groups = parser.parse("two days after christmas at 19");
for (DateGroup group: groups) {
List<Date> dates = group.getDates();
for (Date date: dates) {
Log.e("DATE", date.toString());
}
}
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
一切似乎都很好，它可以在适当的时间内解析日期......但编译需要将近 5 分钟！如果这是编译依赖项的一次性场景，那将是可以的。但是每次我在我的活动课上改变任何东西都需要 5 分钟。这是不可接受的。
IntelliJ 表示它花费最多时间“执行 DEX”。编译输出很多警告信息：
Information:Compilation completed successfully with 41 warnings in 4 min 47 sec
Information:0 errors
Information:41 warnings
Warning:Android Dex: [helloworld] warning: Ignoring InnerClasses attribute for an anonymous inner class

Warning:Android Dex: [helloworld] solution is to recompile the class from source, using an up-to-date compiler
Warning:Android Dex: [helloworld] and without specifying any "-target" type options. The consequence of ignoring
Warning:Android Dex: [helloworld] this warning is that reflective operations on this class will incorrectly
Warning:Android Dex: [helloworld] indicate that it is *not* an inner class.

有什么办法可以加快速度吗？也许android:dex不必每次都调用？或者也许有一种方法可以“正确地”编译依赖项？
这是我的pom.xml文件，如果有帮助的话：
