Description

I am unable to set the compression method per archive entry. In my example I try to switch from LZMA2 to COPY for the second entry. But 7zip says that both entry has COPY as compression method.

public static void main(String args[]) throws Exception {
		String t = "Das ist ein kleiner Test!";

		SevenZOutputFile sevenZOutput = new SevenZOutputFile(new File(
				"c:/tmp/test.7z"));
		sevenZOutput.setContentCompression(SevenZMethod.LZMA2);
		SevenZArchiveEntry entry = new SevenZArchiveEntry();
		entry.setName("test");
		sevenZOutput.putArchiveEntry(entry);
		sevenZOutput.write(t.getBytes());
		sevenZOutput.closeArchiveEntry();
               sevenZOutput.setContentCompression(SevenZMethod.COPY);	
		entry = new SevenZArchiveEntry();
		entry.setName("test2");
		sevenZOutput.putArchiveEntry(entry);
		sevenZOutput.write(t.getBytes());
		sevenZOutput.closeArchiveEntry();
		sevenZOutput.finish();	
		sevenZOutput.close();
	}
