我正在开发一个将从 tar.gz 文件中获取信息的软件,并且我正在使用 Apache commons-compress 库。但是我收到以下错误:
Caused by: java.lang.IllegalArgumentException: Invalid byte 4 at offset 0 in 'O�!�C' len=8
at org.apache.commons.compress.archivers.tar.TarUtils.parseOctal(TarUtils.java:134)

使用的示例 tar.gz 文件是 eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz
这是使用库的类:
public class TarGzBuildAdapter extends BuildAdapter {
public TarGzBuildAdapter(File build) {
super(build);
}
@Override
public List<ArtifactInfo> getArtifactInfos() throws IOException {
TarArchiveInputStream tarArchiveInputStream = new TarArchiveInputStream(
new FileInputStream(this.build));
TarArchiveEntry tarArchiveEntry;
List<ArtifactInfo> artifactInfos = new LinkedList<ArtifactInfo>();
while ((tarArchiveEntry = tarArchiveInputStream.getNextTarEntry()) != null) {
System.out.println(String.format("Name: %s LinkName: %s Size: %Ld RealSize: %Ld",
tarArchiveEntry.getName(), tarArchiveEntry.getLinkName(),
tarArchiveEntry.getSize(), tarArchiveEntry.getRealSize()));
artifactInfos.add(new ArtifactInfo(tarArchiveEntry.getName(), tarArchiveEntry
.getRealSize()));
}
tarArchiveInputStream.close();
return artifactInfos;
}
}
最佳答案
您读取了文件,它不是 TAR 而是 GZ 流。您需要先解压缩它,然后才能使用 TarArchiveInputStream
。
tarArchiveInputStream = new TarArchiveInputStream(
new GzipCompressorInputStream(
new BufferedInputStream(
new FileInputStream(fileName))));
