Publish to Maven Central
Unless stated otherwise the following steps are implemented using bash scripts.
-
Sources:The sources are hosted in https://git.eclipse.org/c/platform/eclipse.platform.releng.git/tree/publish-to-maven-central
-
script: CBIaggregator.sh
-
aggregation model: SDK4Mvn.aggr
-
-
Build Job:This script drives the hudson job https://hudson.eclipse.org/releng/view/Publish%20to%20Maven%20Central/job/CBIaggregator
- unpack Eclipse SDK for use as director application (can we use a smaller installation?)
- install the cbiAggregator
- the aggregation model basically pulls everything from a given release repo
- configure for all operating systems
- specifies these properties: packedStrategy="UNPACK_AS_SIBLING" mavenResult="true" versionFormat="MavenRelease"
- define maven mappings to map all 3rd party artifacts to their
original GAV, as of SDK Neon.2 these are:
- com/jcraft/jsch/0.1.53
- com/ibm/icu/icu4j/56.1.0
- commons-jxpath/commons-jxpath/1.3.0
- javax/inject/javax.inject/1.0.0
- junit/junit/4.12.0
- org/apache/xmlgraphics/batik-css/1.7.0
- org/apache/lucene/lucene-analyzers/3.5.0
- org/apache/lucene/lucene-core/3.5.0
- org/apache/felix/org.apache.felix.gogo.runtime/0.10.0
- org/apache/felix/org.apache.felix.gogo.shell/0.10.0
- org/apache/ant/ant/1.9.6
- org/tukaani/xz/1.3.0
- org/ow2/sat4j/org.ow2.sat4j.core/2.3.5
- org/ow2/sat4j/org.ow2.sat4j.pb/2.3.5
- org/ow2/asm/asm-tree/5.0.1
- org/ow2/asm/asm/5.0.1
- Since Neon.3 some of the above specify Version Pattern/Template in order to cut of undesired ".0" parts, so junit, e.g., is now 4.12, not 4.12.0
- p2-only content: p2.index p2.packed content.jar artifacts.jar
- all features (irrelevant in plain maven use):
*feature.group
and*feature.jar
- test plug-ins:
org/eclipse/*/*test*
-
tooling*
(what is this?) - directories containing a pom but no corresponding jar file
- "garbage", i.e., 3rd party artifacts that after previous clean-up are no longer referenced from any org/eclipse/{platform,jdt,pde} pom files
- directories that are empty after previous clean-up
Technically, some of the clean-up is not necessary, but it helps to give a good picture of what will be published.
This step is implemented as a small Java tool.
- Sources:The sources are hosted in
https://git.eclipse.org/c/platform/eclipse.platform.releng.git/tree/publish-to-maven-central,
see
src/
andenrichPoms.jardesc
Build Job:The tool is built on the fly from CBIaggregator.sh:264 (during hudson job CBIaggregator)
Add some required information to the generated poms:
- dynamic content (retrieved mostly from MANIFEST.MF):
- name (typically matches what the aggregator filled in as description)
- url
- scm connection, tag and url
- semi dynamic content
- developers (start from the git url, and match it against known project names to link to the corresponding "Who's Involved" page of PMI)
- static content
- copyright
- license
- organization
- issue management
- hard wired corrections
- scm connection for emf & ecf
- fix name of
org.eclipse.core.resources.win32.x86*
fragments
- fix checksums (md5 & sha1 after pom update -- not needed for publishing)
Use a heuristic mapping from bundle name to name of the doc bundle holding corresponding javadoc, one of:
- org.eclipse.jdt.doc.isv
- org.eclipse.pde.doc.user
- org.eclipse.platform.doc.isv
Then
- create a README.txt referring to the doc bundle
- jar the README.txt
- copy the jar to the locations so that it will be picked up by maven
Workaround for sources artifacts missing for 8 artifacts ().
- org.eclipse.core.net.win32.x86_64
- org.eclipse.core.net.win32.x86
- org.eclipse.core.net.linux.x86_64
- org.eclipse.core.net.linux.x86
- org.eclipse.tips.ui
- org.eclipse.tips.json
- org.eclipse.tips.ide
- org.eclipse.tips.core
Create sources jars:
- check out sources from git
- respect content of build.properties
- manually jar it up and put it into the location expected by maven
-
hudson jobs:
Steps:
- copy relevant section of prepared repo into current hudson workspace
- for each
*.pom
,*.jar
,*-sources.jar
and*-javadoc.jar
- invoke maven (cli)
- pass settings configured for GPG signing and OSSRH account
(
-s
). - use a generic pom (
-f
) (configuremaven-gpg-plugin
andnexus-staging-maven-plugin
(is the latter needed here?))
- call goal
gpg:sign-and-deploy-file
- passing these properties (
-D
):url, repositoryId, file, pomFile, classifier
- pass settings configured for GPG signing and OSSRH account
(
- invoke maven (cli)
Caveat:
If gpg:sign-and-deploy-file
doesn't work for some reason, it's
tempting to try manual upload of artifacts instead. This, however,
doesn't seem to scale, i.e., it's OK for one artifact, but not for a
significant number of artifacts. See how I struggled : OSSRH-27091
comment 389077
(look for item (2)).
- Login to OSSRH nexus (personal account must have been assigned permissions for the targeted staging area, simply request this in the Jira ticket).
- Identify and select the staging repository created by the previous
step (name is group-without-dots-dash-number, where number starts
at 1000, e.g.,
orgeclipseplatform-1005
) - Click close, and wait for validation results to appear under "Activity"
- On success click release, otherwise click drop, fix errors and try again
