Java 编译 .java 并显示 'extends' 失败

Question

我正在尝试在 OSX 上编译 here 的 pentaho 示例.

Sample1.java扩展 AbstractReportGenerator.java。

我已在控制台中导出 CLASSPATH 以包含密码:

export CLASSPATH=/Users/xxx/java-dev/pentaho/:/Users/xxx/java-dev/pentaho/lib/

我已使用 javac 成功地将 AbstractReportGenerator.java 编译到与 Sample1.java 文件相同的文件夹中，但是当我尝试编译 Sample1.java 时，它总是失败，并出现 3 个与 AbstractReportGenerator 相关的错误。

关于原因和解决方案有什么建议吗？

文件夹结构:

Working Folder >
 - Sample1.java
 - AbstractReportGenerator.java
 - AbstractReportGenerator.class
 - AbstractReportGenerator$1.class
 - AbstractReportGenerator$OutputType.class
 - lib
   - pentaho .jar files

命令:

javac -cp "lib/*" Sample1.java
Sample1.java:41: error: cannot find symbol
public class Sample1 extends AbstractReportGenerator
                             ^
  symbol: class AbstractReportGenerator
Sample1.java:61: error: cannot find symbol
      final ClassLoader classloader = this.getClass().getClassLoader();
                                          ^
  symbol: method getClass()
Sample1.java:132: error: package AbstractReportGenerator does not exist
    new Sample1().generateReport(AbstractReportGenerator.OutputType.PDF, outputFilename);
                                                        ^
Note: Sample1.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
