> Compress - ZipArchive - unpack() : IOException while unpacking due to missing

> Key: SANDBOX-196
> URL: https://issues.apache.org/jira/browse/SANDBOX-196
> Project: Commons Sandbox
> Issue Type: Bug
> Components: Compress
> Affects Versions: Nightly Builds
> Environment: Linux
> Java(TM) SE Runtime Environment (build 1.6.0-b105)
> Reporter: Christian Scheid
>
> In the current snapshot of the ZipArchive class of commons compress seems to
> be an OS/VM-related problem with the unpack() method of ZipArchive.
> I got an IOException using unpack() for a simple jar-archive.
> I figured out that the files from the ZipEntries couldn't be created because
> of missing parent directories.
> I fixed the problem by including the usage of the forceMkdir() of the
> commons-io FileUtils class in the unpack() method. In case you want to use my
> fix:
> // ... for every entry
> File outFile = new File(fosString);
> if (outFile.getParentFile() != null && !outFile.getParentFile().exists()) {
> FileUtils.forceMkdir(outFile.getParentFile());
> }
> FileOutputStream fos = new FileOutputStream(outFile);
> // ... write to filestream
> best regards,
> chris
