Dear Channy,

you saved my day! At least after changing the Realm of the "Additional Credentials" to the simplified form "svn+ssh://server-name" which you provided, it looks quite promising that it finally works for me.

Best regards and thanks for the thorough analysis.

Hello,

for me it's works with svn+ssh but not with https.
I try to add :
{{additionalCredentials: [
[realm: 'My Realm SVN',
credentialsId: 'myId'],
[realm: 'https://192.168.XX.YY:443',
credentialsId: 'myId'],
[realm: 'https://192.168.XX.YY',
credentialsId: 'myId']
]}}
And i still have:

My versions are:

• Jenkins 2.7.3
• SVN plugin 2.7.1

So how, i can help you better? (Maybe I can try to do PR, if i can restart the production jenkins in java remot debug....)

Hello, I try to reproduce with a unit test directly on my svn server. com.myapp.server contains 2 externals : com.myapp.server.webapp and another one. But the error not occured.
The changelog file is always empty (<log/>) maybe i must do another previous call to feed it.
How this following test is different as a checkout directly by jenkins 2 ? :

{{
@Test(timeout = 0L)
public void testCheckoutHttpsWithExternalsAndAuthentification() throws Exception {
SystemCredentialsProvider.getInstance().setDomainCredentialsMap(Collections.singletonMap(Domain.global(),
Arrays.<Credentials>asList(
new UsernamePasswordCredentialsImpl(CredentialsScope.GLOBAL, "1-login", null, "mylogin", "mypassword")
)
));

List<SubversionSCM.ModuleLocation> locations = Arrays.asList(
new SubversionSCM.ModuleLocation("https://192.168.XX.YY/repos/svnflow/myproject/trunk/server/com.myapp.server", "1-login",".", SVNDepth.INFINITY.getName(), false)
);
List<SubversionSCM.AdditionalCredentials> additionalCredentials = Arrays.asList(
new SubversionSCM.AdditionalCredentials("Realm of SVN","1-login"),
new SubversionSCM.AdditionalCredentials("https://192.168.XX.YY:443","1-login"),
new SubversionSCM.AdditionalCredentials("https://192.168.XX.YY","1-login"),
new SubversionSCM.AdditionalCredentials("https://192.168.XX.YY/repos/svnflow","1-login"),
new SubversionSCM.AdditionalCredentials("https://192.168.XX.YY/repos/svnflow/myproject/trunk/server/com.myapp.server.webapp","1-login")
);
SCM scm = new SubversionSCM(locations, new UpdateUpdater(), null, null, "", "", "", "", false, false, additionalCredentials);
SCMSource source = new SingleSCMSource(null, "https://192.168..XX.YY/repos/svnflow/myproject/trunk/server/com.myapp.server", scm);
TaskListener listener = StreamTaskListener.fromStdout();
// First check fetching of all heads. SCMHeadObserver.Collector.result is a TreeMap so order is predictable:
assertEquals("[SCMHead

]", source.fetch(listener).toString());
// SCM.checkout does not permit a null build argument, unfortunately.
Run<?,?> run = r.buildAndAssertSuccess(r.createFreeStyleProject());
// Retrieval of heads:
FilePath ws = new FilePath(new File("C:\\Users\\gdufour\\AppData\\Local\\Temp\\hudsonFixedtest\\jobs\\test0\\builds
1")).child("tmp");
Launcher launcher = new Launcher.LocalLauncher(listener);
SCMRevisionState scmRevisionState = scm.calcRevisionsFromBuild(run , ws, launcher, listener);
assertRevision2(source.fetch(new SCMHead("https://192.168.XX.YY/repos/svnflow/myproject/trunk/server/com.myapp.server"), listener), "null", source, run, listener, launcher, scmRevisionState);
}

private void assertRevision2(@CheckForNull SCMRevision rev, @CheckForNull String expectedFile, @NonNull SCMSource source, @NonNull Run<?,?> run, @NonNull TaskListener listener, Launcher launcher, SCMRevisionState scmRevisionState) throws Exception {
if (rev == null)

FilePath ws = new FilePath(new File("C:\\Users\\gdufour\\AppData\\Local\\Temp\\hudsonFixedtest\\jobs\\test0\\builds
1")).child("tmp");
File changelog = new File("C:\\Users\\gdufour\\AppData\\Local\\Temp\\hudsonFixedtest\\jobs\\test0\\builds\\1
changelog");
source.build(rev.getHead(), rev).checkout(run, launcher, ws, listener, changelog, scmRevisionState);
FilePath file = ws.child("file");
assertEquals(expectedFile, file.exists() ? file.readToString() : null);
}}}

So i debug the plugin and i found why. It's because the format of the realm is not just the realm name but the full name with uri like:
<https://XX.YY.WW.ZZ:PORT> My Realm Name
So it's my fault. sorry

I see no reason for this to have been reopened.
