Bug 568923 - add activity for TM terminal main toolbar button This change adds an extra activity for the TM terminal main toolbar contribution. This allows applications to disable the contribution without disabling the rest of TM terminal functionality. With this change, disabling of the TM terminal main toolbar button can be done with a product customization file containing the line: org.eclipse.ui.workbench/UIActivities.org.eclipse.tm.terminal.view.ui.activity.maintoolbar=false The product customization file is specified to Eclipse arguments: -pluginCustomization /some/path/plugin_customization.ini Change-Id: Id1c34616f4f2a0ac77edbfe201c1db095f9ce7b8 Signed-off-by: Simeon Andreev <firstname.lastname@example.org>

Most developers, developing CDT in the Eclipse IDE, should use Getting_started_with_CDT_development.
Eclipse CDT uses the standard Maven and Tycho workflow for building CDT using Maven 3.6.0 and Java 8. Therefore to package CDT do:
and the resulting p2 repository will be in
The current set of options to Maven used for building on the CI can be seen in the Jenkinsfiles on cdt-infra
To build CDT plug-ins you need a standard Maven & Java developement environment. The Dockerfiles used for CDT's images are published in cdt-infra. The requirements for running all tests successfully and for rebuilding non-Java parts of CDT are much more extensive than standard Maven & Java and include items such as GCC, GDB, yarn, Node, etc. Refer to the Dockerfiles for the current versions of those dependencies.
There are a number of profiles (-P to mvn) to control the behaviour of the build.
Individual p2 repos can be turned on and off to allow building CDT, or parts of CDT against different target platforms easily. For example, you can:
mvn verify -DuseSimrelRepo -f debug/org.eclipse.cdt.debug.application.product
build-standalone-debugger-rcp profile will include the standalone debugger, located in
Using any of the above profiles can skip large sets of tests. The CI build uses this to parallelize tests. See https://ci.eclipse.org/cdt/view/Gerrit/
baseline-compare-and-replace profile controls whether baseline replace and compare is performed. On a local build you want to avoid baseline replace and compare, especially if you have different versions of Java than the baseline was built with.
If you have the same version of Java as the build machine you can run baseline comparison and replace. To do that run with the
Requires verify phase of maven to run, i.e. will not run with
mvn package even if profile is specified.
Runs the production steps of the build. This profile can only be run on the CDT CI machines as access to Eclipse key signing server is needed to sign the jars.
Some of the help systems in Eclipse CDT require the
regenHelp profile to rebuild their HTML from the source documents. For example, to regenerate the help for Autotools or Meson do:
mvn generate-resources -DuseSimrelRepo -f build/org.eclipse.cdt.meson.docs -PregenHelp
mvn generate-resources -DuseSimrelRepo -f build/org.eclipse.cdt.autotools.docs -PregenHelp
jniheaders profile can be used on the
native/org.eclipse.cdt.native.serial to rebuild the header files for JNI natives. See also
native property below.
There are a number of properties (-D to mvn) to control the behaviour of the build. Refer to the pom.xml for the full list. Many of the properties are not intended to be set at the command line.
Documentation generation for CDT can be time consuming. For local builds this can be skipped with
Running tests for CDT can be time consuming. For local builds this can be skipped with
Running a build with uncommitted changes will normally cause an error. To run a build with uncommited changes use
For running CDT's DSF-GDB tests, this specifies the path to the location of gdb.
For running CDT's DSF-GDB tests, this specifies the executable names of the gdbs to run, comma-separated.
native property can be used to build the native libraries. Defining the
native property will activate profiles to add the extra steps to compile the natives libraries used by CDT. The main CDT build by default will not build the libraries, but instead use the versions of the libraries checked into git. Therefore when users modify the sources of the native libraries, they have to build and commit the changed library binaries as part of the commit.
releng/scripts/check_code_cleanliness.sh, which is run on the build machine as part of the gerrit and main build flows, will ensure that the libraries that are checked in are indeed up to date with their sources.
native property can be one of the following:
linux.x86_64- uses local tools and builds only linux.x86_64 libraries
linux.ppc64le- uses local tools and builds only linux.ppc64le libraries
docker- uses CDT's docker releng images to do the native builds for all platforms
all- uses local tools to do the native builds for all platforms
Therefore to build all the natives using docker add
-Dnative=docker to your maven command line (e.g.
mvn verify -Dnative=docker).
To build only the native libraries
mvn process-resources can be used on the individual bundles with the simrel target platform, e.g.:
mvn process-resources -Dnative=docker -DuseSimrelRepo -f native/org.eclipse.cdt.native.serial
mvn process-resources -Dnative=docker -DuseSimrelRepo -f core/org.eclipse.cdt.core.native
However, the challenge is that dll files on Windows have a timestamp in them. To have reproducible builds, we need to have a reproducible timestamp. As Microsoft has moved away from using a timestamp to rather use a hash of the source files as the value, we therefore hash the source files used by the library and the header files for the Java API and use that as the value.
An additional tip is to set the following in
.gitconfig to allow you to diff
.dll files. This will show the timestamp of the DLL in the diff as part of the DLL headers.
[diff "dll"] textconv = objdump -x binary = true
When the host is Windows, getting docker to behave as encoded in the pom.xml may be challenging, instead a command like this will probably work (replace your path to git root). Note that running this in git bash causes problems because of the /work in the command line arguments. (TODO integrate this command line way of running into the pom.xml so the original instructions work.)
docker 'run' '--rm' '-t' '-v' 'D:\cdt\git\org.eclipse.cdt:/work' '-w' '/work/core/org.eclipse.cdt.core.native' 'quay.io/eclipse-cdt/cdt-infra-eclipse-full:latest' 'make' '-C' 'native_src' 'rebuild'
