我正在編寫一個eclipse插件並且項目環境配置正確（我相信）。Eclipse插件開發問題
我能夠在沒有任何編譯時錯誤的情況下編譯解決方案。以下是調試解決方案時拋出異常的代碼片段。我確信所有必需的插件和外部罐子都已正確配置。
我已經嘗試了幾乎所有的方法，用戶在互聯網上建議，沒有任何工作。 （我甚至根據他們的建議更改了代碼）。
所以要求你讓我知道爲什麼我得到低於錯誤的原因，並建議替代方法。
public static IProject getCurrentSelectedProject() {
try {
IWorkspace workspace = ResourcesPlugin.getWorkspace();
IProject[] projects = workspace.getRoot().getProjects();
for (int i = 0; i < projects.length; i++) {
IProject project = projects[i];
if ((project.isOpen())) {
return project;
}
}
} catch (Throwable ex) {
ex.printStackTrace();
}
return null;
}
下面是我收到

ÿ我們的錯誤說Eclipse無法找到ResourcesPlugin類。您是否將org.eclipse.core.resources指定爲插件清單中的擴展？ –
