Prepare

Use Erlang R20 later

The build scripts uses kerl, so no specific installation is needed, unless manually building it using rebar.

https://www.erlang-solutions.com/downloads/
sudo apt remove esl-erlang
sudo apt install ~/Downloads/esl-erlang_25.0.4-1_ubuntu_focal_amd64.deb

Other:
sudo apt install ~/Downloads/esl-erlang_24.3.3-1_ubuntu_focal_amd64.deb
sudo apt install ~/Downloads/esl-erlang_23.3.4.5-1_ubuntu_focal_amd64.deb

Java 8

sudo apt-get install openjdk-8-jdk
sudo update-alternatives --config java

Set path:
export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

Maven is the used build tool, see `~/.m2` for cached packages.

Eclipse 4.9+

https://www.eclipse.org/downloads/packages/installer or

sudo snap install --classic eclipse

gives ~ Eclipse 2022-12 (4.26)

Installed plugins can be located at: ~/snap/eclipse/66/amd64

Ruby

Needed by erlide_eclipse

> Setup rbenv
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'eval "$(~/.rbenv/bin/rbenv init - zsh)"' >> ~/.zshrc
restart shell

> Setup ruby-build
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

> Setup older ruby 2.7.1 (setup_tools.sh indicates 2.1.2 which not working..)
rbenv install 2.7.1
rbenv global 2.7.1
restart shell

Install

Details

erlide_kernel

Findings

  • Uses kerl, copied to ~/erlide_tools
  • Kerl does only support 2 prior releases
  • Using a older kerl fails erlang builds anyway..
  • Rebar in repo: rebar 3.4.3 OTP-16702: To enable more optimizations, BEAM files compiled with OTP 21 and earlier cannot be loaded in OTP 25.

Build

./build
./build test
cd eclipse
./build

The build result is found at: eclipse/org.erlide.kernel.site-<VERSION>.zip

which can be unzipped to the update site:

update/kernel/<VERSION>/

Like update/kernel/0.115.5/

erlide_eclipse

Build

Use OTP23/24 if testing older erlide versions

> Build via makefile
make build

> Deploy via makefile
make deploy

> From Jenkinsfile
./mvnw -B -U clean verify -P help,build-product -Dmaven.test.failure.ignore=true

> From Github Actions
./mvnw -B -U clean verify -P help

> Build without running tests (~49s)
./mvnw -B -U clean -P help

> Build with full logs: -X

jinterface

Not using OTPs lib/jinterface/priv/OtpErlang.jar

Update:

  • Copy source: cp ~/.kerl/builds/25.2/otp_src_25.2/lib/jinterface/java_src/com/ericsson/otp/erlang/* libs/com.ericsson.otp.jinterface/src/com/ericsson/otp/erlang/
  • Update version, Use version from: ~/.kerl/builds/25.2/otp_src_25.2/lib/jinterface/vsn.mk:JINTERFACE_VSN = 1.13.1
  • Update version in files: libs/com.ericsson.otp.jinterface/pom.xml libs/com.ericsson.otp.jinterface/META-INF/MANIFEST.MF

Interesting commits

update kernel to 0.115.3 e63e12dc7456b2ea2108e86124037f2711d2adb3 v0.55.0 (which includes change to 0.115.3) 9965e654e82058a11bbbea64171ad5c30419bb4e

TODO

  • Avoid commit in eclipse/build.sh
  • Add otp23 and 24 as debugger target
  • Replace rebar_localdep plugin (results in warnings, and crash?)
  • Lift Java
  • Lift ruby: erlide_eclipse/plugins/org.erlide.help/Gemfile.lock "lockfile was generated with 2.1.4" but 2.7.1 in: erlide_eclipse/.ruby-version
  • Ruby issue "Gemfile:5: warning: calling URI.open via Kernel#open is deprecated, call URI.open directly or use URI#open"
  • Upstream warning fixes to Erlang JInterface
  • Update kernel version banner on https://erlide.org/ (via metafile?)
