我正在尝试使用 JGit 库将我的 android 手机上的文档同步到服务器。
它几乎可以工作......但我无法承诺工作。每当我尝试提交时，我都会收到异常“数据错误”。我将问题追溯到 org.eclipse.jgit.util.IO 中的以下语句：
public static void readFully(final InputStream fd, final byte[] dst,
int off, int len) throws IOException {
while (len > 0) {
final int r = fd.read(dst, off, len);
if (r <= 0)
throw new EOFException(JGitText.get().shortReadOfBlock);
off += r;
len -= r;
}
}
行 fd.read(dst, off, len) 将抛出执行。我认为 fd 参数是 InflaterInputStream 所以这段代码试图从压缩档案中读取。
我试图在装有 Android 2.2 的 HTC Desire Z 上运行它。
我正在使用 org.eclipse.jgit-0.12.1.jar 和 com.jcraft.jsch_0.1.31.jar 来访问 jgit 功能。
我已经做了一些测试示例来尝试理解问题
以下代码在我的 Windows XP 机器上运行没有问题：
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
try {
// Create a new directory
File dirF = new File("C:\\Test\\TestDir");
dirF.mkdir();
log(">>> Created directory.\n");
// Initialize git repository
InitCommand init = Git.init();
File initFile = new File("C:\\Test\\TestDir");
init.setDirectory(initFile);
init.call();
log(">>> Git Init done.\n");
// Create a file
File newfile = new File("C:\\Test\\TestDir\\myfile.txt");
newfile.createNewFile();
PrintStream os = new PrintStream(newfile);
os.println("Some text");
os.close();
log(">>> File created.\n");
// Add to git
FileRepositoryBuilder builder = new FileRepositoryBuilder();
File f = new File("C:\\Test\\TestDir\\.git");
Repository db = builder.setGitDir(f)
.findGitDir() // scan up the file system tree
.build();
Git git = new Git(db);
AddCommand add = git.add();
add.addFilepattern(".").call();
log(">>> Git Add done.\n");
// Commit the change
CommitCommand commit = git.commit();
commit.setAll(true);
commit.setMessage("A JGit message");
commit.call();
log(">>> Git Commit done.\n");
// Check the log
for (RevCommit c : git.log().call()) {
log(c.getId() + "/" + c.getAuthorIdent().getName() + "/"
+ c.getShortMessage());
}
} catch (Exception e) {
e.printStackTrace();
}
}
private static void log(String s) {
System.out.print(s);
}
}
以下代码将在我的 android 手机上引发异常：
public class JGitSimpleAndroidActivity extends Activity {
StringBuilder sb;
TextView tv;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sb = new StringBuilder();
tv = new TextView(this);
try {
// Create a new directory
File sdCard;
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
sdCard = Environment.getExternalStorageDirectory();
} else {
log(">>> SD card is not available.");
return;
}
File dirF = new File(sdCard,"TestDir");
dirF.mkdir();
log(">>> Created directory.\n");
// Initialize git repository
InitCommand init = Git.init();
init.setDirectory(dirF);
init.call();
log(">>> Git Init done.\n");
// Create a file
File newfile = new File(dirF,"myfile.txt");
newfile.createNewFile();
PrintStream os = new PrintStream(newfile);
os.println("Some text");
os.close();
log(">>> File created.\n");
// Add to git
FileRepositoryBuilder builder = new FileRepositoryBuilder();
File f = new File(dirF,".git");
Repository db = builder.setGitDir(f)
.findGitDir() // scan up the file system tree
.build();
Git git = new Git(db);
AddCommand add = git.add();
add.addFilepattern(".").call();
log(">>> Git Add done.\n");
// Commit the change
CommitCommand commit = git.commit();
commit.setAll(true);
commit.setMessage("A JGit message");
commit.call(); // >>>>>>>> EXCEPTION THROWN HERE <<<<<<<
log(">>> Git Commit done.\n");
// Check the log
for (RevCommit c : git.log().call()) {
log(c.getId() + "/" + c.getAuthorIdent().getName() + "/"
+ c.getShortMessage());
}
} catch (Exception e) {
log(e.getMessage());
}
}
private void log(String s) {
sb.append(s);
sb.append('\n');
tv.setText(sb);
setContentView(tv);
}
}
关于我可以做些什么来完成这项工作的任何想法？
问候，安德斯
