java - Eclipse 启动时出现 NumberFormatException

Question

我是 Java 和 eclipse IDE 的新手。我正在尝试为我安装的 eclipse 4.4.0 创建一个插件 the official IBM article 。我已将插件描述添加到plugin.xml:

<extension point="org.eclipse.debug.core.launchConfigurationTypes">
    <launchConfigurationType
        name="MyConfiguration"
        delegate="com.myplugin.first.launching.MyLaunchConfiguration"
        modes="run, debug"               
        id="com.myplugin.first.launching.myConfiguration">        
    </launchConfigurationType>
</extension>

我已经创建了具有所需依赖项的空配置委托(delegate)。不幸的是，我无法使用我的插件启动新的 Eclipse 应用程序，因为每次我都会收到以下错误:

    java.lang.NumberFormatException: For input string: ""        at java.lang.NumberFormatException.forInputString(Unknown Source)        at java.lang.Integer.parseInt(Unknown Source)        at java.lang.Integer.parseInt(Unknown Source)        at org.eclipse.osgi.storagemanager.StorageManager.updateTable(StorageManager.java:511)        at org.eclipse.osgi.storagemanager.StorageManager.open(StorageManager.java:708)        at org.eclipse.osgi.storage.Storage.getChildStorageManager(Storage.java:1747)        at org.eclipse.osgi.storage.Storage.getInfoInputStream(Storage.java:1764)        at org.eclipse.osgi.storage.Storage.(Storage.java:124)        at org.eclipse.osgi.storage.Storage.createStorage(Storage.java:84)        at org.eclipse.osgi.internal.framework.EquinoxContainer.(EquinoxContainer.java:75)        at org.eclipse.osgi.launch.Equinox.(Equinox.java:31)        at org.eclipse.core.runtime.adaptor.EclipseStarter.startup(EclipseStarter.java:297)        at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:232)        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)        at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)        at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)        at java.lang.reflect.Method.invoke(Unknown Source)        at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:648)        at org.eclipse.equinox.launcher.Main.basicRun(Main.java:603)        at org.eclipse.equinox.launcher.Main.run(Main.java:1465)        at org.eclipse.equinox.launcher.Main.main(Main.java:1438)    An error has occurred. See the log file    null.

我没有找到有错误的日志文件。怎么了？我该怎么办？

也许有人知道这个问题。

尝试删除 eclipse\configuration 文件夹中除 config.ini 之外的所有内容，然后启动 Eclipse。还可以粘贴 eclipse\configuration 中最新日志文件的内容以获取完整的错误。
