我寫了一個Ant任務生成一個Eclipse .userlibraries文件。您可以導入生成的文件以在Eclipse中創建用戶庫。然後將此用戶庫用作構建路徑的一部分。
使用任務添加到您的Ant構建文件：
<target name="createEclipseUserLibraries"
description="Creates classpath and bootclasspatch that can be imported into Eclipse">
<taskdef name="createEclipseUserLibraries"
classname="com.forumsys.tools.CreateEclipseUserLibraries"
classpathref="yourclasspathref"/>
<createEclipseUserLibraries classpathref="classpathref" bootclasspathref="bootclasspathref"/>
</target>
Ant任務。它需要ant.jar來運行和編譯：
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.Task;
import org.apache.tools.ant.types.Path;
import org.apache.tools.ant.types.Reference;

謝謝，這很有幫助。我很希望有人已經開發出你描述的那種腳本。特別是，這些構建文件有很多條件包含，我想自動解決它們。 – 2010-03-16 15:09:58
