[m2e-users] How to enable strong cipher suites for m2e plug-in

Wed, 25 Jan 2017 10:23:40 -0800

Can't access to maven repository using strong encryption in Eclipse Luna.
 
Connecting to a new https maven repository uisng Update Project with "Force Update
of Snaphots/Releases" result in error  "handhake_failure"
 
Output from java -version:
Java(TM) SE Runtime Environment (build pwa6480sr3fp10-20160720_02
(SR3fp10))
IBM J9 VM (build 2.8, JRE 1.8.0 Windows 7 amd64-64 Compressed
References 20160719_312156 (JIT enabled, AOT enabled)
J9VM - R28_Java8_SR3_20160719_1144_B312156

J9CL - 20160719_312156)
JCL - 20160719_01 based on Oracle jdk8u101-b13
 
- The error occurs when running Maven - Update Project with "Force Update of Snaphots/Releases".
- Executing a maven build with Run As - maven build works fine.

Their repository allows the following cipher suites (openssl names):
tls1_2: ECDHE-RSA-AES256-GCM-SHA384
tls1_2: ECDHE-RSA-AES256-SHA384
tls1_2: ECDHE-RSA-AES128-GCM-SHA256
tls1_2: ECDHE-RSA-AES128-SHA256
 
m2e uses only the following cipher suite (from console output captured running with -Djavax.net.debug=ssl:handshake)
SSL_RSA_WITH_3DES_EDE_CBC_SHA
 
Their IT Security department does not allow the use of this weaker cipher suite in their organization, so downgrading on the
server side is not an easy option.
 
I  really appreciate your help.
 
Regards.
