Maven https errors with RAD/Eclipse

Question

RAD 9.6.1 (Java 8) on Windows

Maven is the current culprit, but I'm betting this is Eclipse-wide/Java-wide. RAD errors showing this, on the project and pom.xml:

        pom.xml /Mail   line 1  Maven Dependency Problem 

Or, when I run Maven from inside RAD, this:

[ERROR] Failed to execute goal on project Mail: Could not resolve dependencies for project com.ibm.gs.houston:Mail:adapter:1.0-SNAPSHOT: Failed to collect dependencies at com.itextpdf:itext-licensekey:jar:2.0.3: Failed to read artifact descriptor for com.itextpdf:itext-licensekey:jar:2.0.3: Could not transfer artifact com.itextpdf:itext-licensekey:pom:2.0.3 from/to iText (https://repo.itextsupport.com/releases): No appropriate protocol, may be no appropriate cipher suite specified or protocols are deactivated -> [Help 1]

I suspect it's not just this site, but any site that no longer supports SSLv3. I've seen this in WebSphere too, when it had a setting to "SSL_TLS", which apparently doesn't do TLS 1.1 or 1.2. Finding what I hoped was the right RAD property file to address that setting, didn't seem to make any difference.

From the Eclipse configuration details, I see:

com.ibm.SSL.ConfigURL=file:C:\Program Files\IBM\SDP/runtimes/base_stub/properties/ssl.client.props

But changing settings there hasn't helped.

Answer 1

This appears to be an Eclipse bug that isn't fixed until a later version than what RAD currently uses:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=515859

Answer 2

An approach that works currently is to update RAD's eclipse.ini to point to a custom java.security file.

Edit the RAD eclipse.ini file to add something like: -Djava.security.properties=/Users/YourUsername/my.java.security

Where my.java.security contains:

# explicitly don't use the WAS-provided SSL factory (from RAD).
# Use -Djava.security.properties=/Users/YourUsername/my.java.security in eclipse.ini
ssl.SocketFactory.provider=
ssl.ServerSocketFactory.provider=

Answer 3

The latest update to RAD 9.6 uses Maven M2E 1.8.3, which does not experience the bug. The solution is to update your RAD 9.6 installation through IBM Installation Manager.
