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