[英]Migration code from 1.6 jdk to 11 jdk problem with sun.net.www.protocol.file
I have a problem with migration old code which used sun.net.*
and sun.net.www.protocol.file.FileURLConnection
Ant cannot build project on jdk 11 because FileURLConnection
is from version 8/9 internal class of base package.我有迁移旧代码的问题,它使用
sun.net.*
和sun.net.www.protocol.file.FileURLConnection
Ant 无法在 jdk 11 上构建项目,因为FileURLConnection
来自版本 8/9 内部 class 基础 ZEFE86B70A8E604A67C FileURLCOnnection was use to check instance of returned class so I will need good idea how I can replace this fragment without destroing logic (fragment belowe). FileURLCONnection 用于检查返回的 class 的实例,所以我需要知道如何在不破坏逻辑的情况下替换这个片段(下面的片段)。
connection instanceof FileURLConnection
for (URL url = null; resources.hasMoreElements()
&& ((url = resources.nextElement()) != null); ) {
try {
connection = url.openConnection();
if (connection instanceof JarURLConnection) {
checkJarFile((JarURLConnection) connection, pckgname,
classes);
} else if (connection instanceof FileURLConnection) {
try {
checkDirectory(
new File(URLDecoder.decode(url.getPath(),
"UTF-8")), pckgname, classes);
} catch (final UnsupportedEncodingException ex) {
throw new ClassNotFoundException(
pckgname
+ " does not appear to be a valid package (Unsupported encoding)",
ex);
}
} else
throw new ClassNotFoundException(pckgname + " ("
+ url.getPath()
+ ") does not appear to be a valid package");
} catch (final IOException ioex) {
throw new ClassNotFoundException(
"IOException was thrown when trying to get all resources for "
+ pckgname, ioex);
}
}
You should be able to replace:您应该能够替换:
connection instanceof FileURLConnection
By:经过:
"file".equals(url.getProtocol())
