From e1b15a3b62259a0a7e8da3561b044dabf3c5e9d4 Mon Sep 17 00:00:00 2001 From: "Timoney, Dan (dt5972)" Date: Thu, 29 Aug 2019 11:11:24 -0400 Subject: Revert "Proposal to remove OSGi dependencies from the CCSDK project" This reverts commit 85041dd8795b84a48d0b48dd746bfbcb230c8794. This needs to be reverted due to insufficient testing (no jUnit tests provided) Change-Id: I011f3eb7ab27ba9946f04d4d528dd4d91b593685 Signed-off-by: Timoney, Dan (dt5972) --- dblib/lighty/pom.xml | 51 -- .../core/dblib/DBLIBResourceProviderLighty.java | 174 ---- .../sli/core/dblib/DBResourceManagerLighty.java | 977 --------------------- .../ccsdk/sli/core/dblib/lighty/DblibModule.java | 56 -- dblib/pom.xml | 1 - 5 files changed, 1259 deletions(-) delete mode 100755 dblib/lighty/pom.xml delete mode 100644 dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/DBLIBResourceProviderLighty.java delete mode 100644 dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/DBResourceManagerLighty.java delete mode 100644 dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/lighty/DblibModule.java (limited to 'dblib') diff --git a/dblib/lighty/pom.xml b/dblib/lighty/pom.xml deleted file mode 100755 index 24db66712..000000000 --- a/dblib/lighty/pom.xml +++ /dev/null @@ -1,51 +0,0 @@ - - - 4.0.0 - - - org.onap.ccsdk.parent - binding-parent - 1.4.1-SNAPSHOT - - - - org.onap.ccsdk.sli.core - dblib-lighty - 0.6.1-SNAPSHOT - jar - - ccsdk-sli-core :: dblib :: ${project.artifactId} - http://maven.apache.org - - - UTF-8 - - - - - - org.onap.ccsdk.sli.core - ccsdk-lighty-dependency-versions - ${project.version} - pom - import - - - - - - - io.lighty.core - lighty-controller - - - org.onap.ccsdk.sli.core - dblib-provider - ${project.version} - - - org.opendaylight.aaa - aaa-encrypt-service - - - diff --git a/dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/DBLIBResourceProviderLighty.java b/dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/DBLIBResourceProviderLighty.java deleted file mode 100644 index 82579d7ec..000000000 --- a/dblib/lighty/src/main/java/org/onap/ccsdk/sli/core/dblib/DBLIBResourceProviderLighty.java +++ /dev/null @@ -1,174 +0,0 @@ -/*- - * ============LICENSE_START======================================================= - * onap - * ================================================================================ - * Copyright (C) 2016 - 2017 ONAP - * ================================================================================ - * Licensed under the Apache License, Version 2.0 (the "License");
