apache-flex - 在项目上运行构建器 'Flex' 时出错

Question

这真让我抓狂。在构建项目时，我收到以下错误

Errors occurred during the build.
    Errors running builder 'Flex' on project 'my-services'.
    java.lang.NullPointerException

这是 Eclipse 中错误日志中的最后一个错误

!ENTRY org.eclipse.core.resources 4 75 2011-09-07 16:07:04.391
!MESSAGE Errors occurred during the build.
!SUBENTRY 1 com.adobe.flexbuilder.project 4 75 2011-09-07 16:07:04.391

我尝试过清理项目、刷新项目、重新启动 Eclipse，甚至将其从我的工作区中删除并重新导入。我还是迷路了。

就我而言，我正在使用模块，并为所有模块创建了一个特殊的输出文件夹。我在日志中收到了这个:

!ENTRY org.eclipse.core.resources 4 75 2012-03-04 10:27:12.328
!MESSAGE Errors occurred during the build.
!SUBENTRY 1 com.adobe.flexbuilder.project 4 75 2012-03-04 10:27:12.328
!MESSAGE Errors running builder 'Flex' on project 'myProject'.
!STACK 0
java.lang.RuntimeException: Object reference not set to an instance of an object.

我能够通过编辑 .project 文件来解决它 - 这看起来会导致如下错误:

...
<linkedResources>
    <link>
        <name>[source path] modules</name>
        <type>2</type>
        <locationURI>DOCUMENTS/modules</locationURI>
    </link>
    <link>
        <name>bin-debug</name>
        <type>2</type>
        <locationURI>DOCUMENTS/modules</locationURI>
    </link>
</linkedResources>
...

希望这可以帮助其他人解决这个烦人的错误。
