我正在尝试根据我的需要修改该答案并使进度监视器正确反映进度。到目前为止我的方法:
import org.eclipse.core.runtime.SubProgressMonitor;
private void configureProject(IProgressMonitor monitor)
throws CoreException, IOException
{
try
{
URL templatesURL = Activator.getDefault().getBundle().getEntry(TEMPLATES);
File templatesFolder = new File(FileLocator.toFileURL(templatesURL).getPath());
int fileCount = getElementsCount(templatesFolder);
monitor.beginTask("Creating file structure for new project...", fileCount + 5);
project.getFolder(P_SRC).delete(true, new SubProgressMonitor(monitor, 1));
project.getFolder(P_BIN).delete(true, new SubProgressMonitor(monitor, 1));
copyFiles(templatesFolder, project, new SubProgressMonitor(monitor, fileCount));
project.getFile(P_TOUCH).delete(true, new SubProgressMonitor(monitor, 1));
IClasspathEntry[] newEntries = new IClasspathEntry[3];
newEntries[0] = JavaCore.newSourceEntry(getCreatedElement().getPath().append(SRC_MAIN));
newEntries[1] = JavaCore.newSourceEntry(getCreatedElement().getPath().append(SRC_RES),
EXCLUDE_ALL);
newEntries[2] = JavaCore.newSourceEntry(getCreatedElement().getPath().append(SRC_TEST));
javaProject.setRawClasspath(newEntries, new SubProgressMonitor(monitor, 2));
}
finally
{
if (!monitor.isCanceled())
monitor.done();
}
}
private int getElementsCount(File file)
{
// return number of files and folders in the file
}
如您所见,我有 3 个用于删除操作的滴答声和 2 个用于设置类路径的滴答声。这是源文件夹中文件的 5 加计数,如果我说:每个文件或文件夹 1 记号。现在我的方法有问题copyFiles
。我修改了相关代码以使用IProgressMonitor
:
private void copyFiles(File srcFolder, IContainer destFolder, IProgressMonitor monitor)
throws CoreException, IOException
{
for (File f : srcFolder.listFiles())
{
if (f.isDirectory())
{
IFolder newFolder = destFolder.getFolder(new Path(f.getName()));
newFolder.create(true, true, new SubProgressMonitor(monitor, 1));
copyFiles(f, newFolder, monitor);
}
else
{
newFile.create(new FileInputStream(f), true, new SubProgressMonitor(monitor, 1));
}
}
}
一旦create(...)
调用其中一种方法( onIFile
或 on IFolder
),进度条应移动 1 个刻度。但它根本不动。可能是什么原因以及如何解决问题?
upd:我将方法修改configureProject
如下:
SubProgressMonitor copyFilesMonitor = new SubProgressMonitor(monitor, fileCount);
copyFilesMonitor.beginTask("Copying files...", fileCount);
copyFiles(templatesFolder, project, copyFilesMonitor);
copyFilesMonitor.done();
现在的问题是,在调用create()
( onIFolder
或 on IFile
)之后,进度条设置为 2/3 - 2 个刻度。2/3 是为整个configureProject()
方法指定的,最后 2 个刻度将由setRawClasspath(...)
尚未完成。
