使用Java打开debian软件包

Question

Java中是否有用于解压缩.deb（debian）压缩文件的库？不幸的是我找不到任何有用的东西。谢谢。

Answer 1

如果您通过解包意味着解压文件，应该可以使用Apache Commons Compress。 .deb文件是“implemented as an ar archive”，Commons Compress能够解压缩存档。

Answer 2

好吧，所以建议我使用apache commons compress，这里有一个方法可以实现。从Maven回购下载：http://mvnrepository.com/artifact/org.apache.commons/commons-compress/1.2。

/** 
* Unpack a deb archive provided as an input file, to an output directory. 
* <p> 
* 
* @param inputDeb  the input deb file. 
* @param outputDir  the output directory. 
* @throws IOException 
* @throws ArchiveException 
* 
* @returns A {@link List} of all the unpacked files. 
* 
*/ 
private static List<File> unpack(final File inputDeb, final File outputDir) throws IOException, ArchiveException { 

    LOG.info(String.format("Unzipping deb file %s.", deb.getAbsoluteFile())); 
    LOG.info(String.format("Into dir %s.", outDir.getAbsoluteFile())); 

    final List<File> unpackedFiles = new LinkedList<File>(); 
    final InputStream is = new FileInputStream(inputDeb); 
    final ArArchiveInputStream debInputStream = (ArArchiveInputStream) new ArchiveStreamFactory().createArchiveInputStream("ar", is); 
    ArArchiveEntry entry = null; 
    while ((entry = (ArArchiveEntry)debInputStream.getNextEntry()) != null) { 
     LOG.info("Read entry"); 
     final File outputFile = new File(outputDir, entry.getName()); 
     final OutputStream outputFileStream = new FileOutputStream(outputFile); 
     IOUtils.copy(debInputStream, outputFileStream); 
     outputFileStream.close(); 
     unpackedFiles.add(outputFile); 
    } 
    debInputStream.close(); 
    return unpackedFiles; 
}
