== Preparation Steps ==

== Building MAT from Sources ==
=== What is done ===
+
Parts of MAT depend on the IBM's DTFJ libraries, therefore one needs the libraries during the build.
+
This preparation step will do the following:
+
* download DTFJ (zipped "old" update site)
+
* publish a p2 repository with DTFJ
+
* modify the target platform definition used for the rest of the build
+
 
+
=== Execution ===
+
* Go in the ''<mat_src>/prepare_build/'' directory
+
* Execute
+
<pre>mvn clean install</pre>
+
* This maven build is using the maven-antrun plugin to download the zip containing DTFJ. If you need to set proxy you can do it using the standard Java settings, i.e. the command line will look like this:
+
<pre>mvn -Dhttp.proxyHost=myProxyHost -Dhttp.proxyPort=myProxyPort clean install</pre>
+
 
+
On the Hudson boxes at Eclipse the settings are defined as $ANT_OPTS
+
 
+
=== Verify ===
+
If the build was successful, then:
+
* ''<mat_src>/prepare_build/target/repository/'' will contain the p2 repository with DTFJ
+
* ''<mat_src>/org.eclipse.mat.targetdef/mat-site.target'' will be modified to point to this repository
+
 
+
== Building MAT ==
+
Once the [[#Preparation Steps]] are done (normally only once) one can run the maven build for MAT.

Introduction

This page describes how Memory Analyzer can be built using Maven/Tycho. The build will

  • build all MAT bundles
  • execute all tests
  • (optional) run FindBugs static checks
  • build eclipse features containing the MAT plugins and produce an update site (p2 repository) with them
  • produce standalone (Eclipse RCP based) products for different OS platforms
  • sign and upload the produced artifacts (when executed on the Eclipse Hudson server)

Prerequisites

Clone the Source Code from Git

MAT sources are in a Git repository, therefore you need a git client. Have a look at MemoryAnalyzer/Contributor_Reference#Get the source

Use Java 1.8 for the Build

The MAT build has to be run with Java 1.8. Make sure the JAVA_HOME environment variable is set to point to a JDK 1.8 installation.

Install and Configure Maven

The Memory Analyzer build requires a Maven 3.0.* installation. It is already present on the Hudson server at Eclipse. For local build one can download it from here.

If you need to set a proxy for Maven, a snippet like this can be added to the Maven settings file:

  <proxies>
    <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <port>8080</port>
      <host>myproxy_host</host>
      <nonProxyHosts>non_proxy_hosts</nonProxyHosts>
    </proxy>
  </proxies>

More information on Maven settings: http://maven.apache.org/ref/3.0.3/maven-settings/settings.html

Building MAT from Sources

Execute the build

  • Open a console and go into the <mat_src>/parent folder (it contains the parent pom.xml)
  • To build MAT with the default profile (build-snapshot) simply execute
mvn clean install
  • This will cause a fresh build of all bundles, execute tests, build eclipse features, an update site (p2 repository) and standalone products
  • If you want to also FindBugs checks are performed as part of the build, then execute
mvn clean install findbugs:findbugs

Where to find the results?

You can find the results of the build in the corresponding .../target/ directories for each plugin, feature, etc... Of particular interest are:

  • <mat_src>/org.eclipse.mat.updatesite/target/site/ - it contains a p2 repository with MAT features
  • <mat_src>/org.eclipse.mat.product/target/products/ - it contains all standalone RCP applications

Building MAT Standalone RCPs from an Existing MAT Update Site

Configure and execute the build

  • Open a console and go into the <mat_src>/parent folder (it contains the parent pom.xml)
  • To produce only the standalone products, using an already existing MAT repository (i.e. without building the bundles again) specify that the build-release-rcp profile is used when you start maven:
mvn clean install -P build-release-rcp
  • It will take the already existing MAT plugins/features from the repository specified by the mat-release-repo-url property in <mat_src>/parent/pom.xml. One can overwrite this location when calling maven. For example, to build products with the older 1.5.0 release, use:
mvn clean install -P build-release-rcp -Dmat-release-repo-url=http://download.eclipse.org/mat/1.5/update-site/

Where to find the results?

You can find the standalone products under <mat_src>/org.eclipse.mat.product/target/products/

Further Information

  • The platforms for which RCPs are built are specified in the <mat_src>/parent/pom.xml file

Known Problems

Wrong file permissions

When building MAT on a Windows box, the RCPs for any other OS will not have the proper permissions (e.g. the executables won't have the x flag). Building under Linux or other non-Windows OS helps.

Hudson Job at Eclipse

The Hudson instance of the Memory Analyzer Project at the Eclise is https://hudson.eclipse.org/mat/.

Snapshot / Nightly builds

The tycho-mat-nightly job checks regularly for changes to the Git repository and produces a snapshot build (see Building MAT from Sources) above

The job is additionally configured to sign the plugins and features in the update site, and to upload all artifacts to the download server. One can download such nightly/snapshot builds here: http://www.eclipse.org/mat/snapshotBuilds.php

Info: Signing is activated by the build-server profile (i.e. with parameter '-P build-server' added to the maven command)

Release Builds

The job mat-standalone-packages can only be triggered manually to build the MAT standalone packages/products using an already existing MAT update site. This can be used in the following scenario - MAT has contributed its bundles and features to the simultaneous Eclipse release as part of a milestone or a release candidate. After the simultaneous release is complete, we would like to have exactly these bundles also packed in the standalone packages, potentially including also the final version of the dependencies (part of the same simultaneous release).

The job is configured to use the build-release-rcp profile when calling maven.
