如何在非 tycho 项目中使用 pomless tycho 工件

How to use pomless tycho artifacts in non-tycho project

我有两个项目:

  1. 使用 pomless Tycho 方法构建的 Eclipse 项目
  2. 一个简单的 Java 项目构建,使用简单的 Maven,没有 OSGI,没有 Tycho

我需要在第二个项目中使用第一个项目中的一些包。我尝试使用 mvn clean install 将第一个项目的 jar 文件安装到本地 Maven 存储库中。并尝试从第二个项目中引用它们。但是我收到以下错误:

Failed to execute goal on project ...: Could not resolve dependencies for project ...: Failed to collect dependencies at bpms:bpms.util.jdk:jar:0.1.0-SNAPSHOT: Failed to read artifact descriptor for bpms:bpms.util.jdk:jar:0.1.0-SNAPSHOT: Failure to find bpms:bundles:pom:1.0.0-SNAPSHOT in https://repo.maven.apache.org/maven2 was cached in the local repository, the resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

bpms.util.jdk-0.1.0-SNAPSHOT.pom 文件包含以下内容:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>bpms</groupId>
    <artifactId>bundles</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>..\.polyglot.pom.tycho</relativePath>
  </parent>
  <artifactId>bpms.util.jdk</artifactId>
  <version>0.1.0-SNAPSHOT</version>
  <packaging>eclipse-plugin</packaging>
  <name>jdk utils</name>
</project>

看来问题是由父神器引起的。是否可以在不参考父 bundles 的情况下将我的工件作为独立工件安装?

什么是正确的做法?我不能使用 pomless Tycho 并且应该为每个包定义一个单独的 pom.xml?

似乎最简单的方法是使用 mvn install:install-file 安装 jar 文件。这是一个可能对某人有用的 bat 文件:

@echo off

set MVN_HOME=C:/Tools/apache-maven-3.6.3
set BUNDLES_HOME=C:/Work/workspace-bpms-trunk/bundles
set ECLIPSE_HOME=C:/Tools/eclipse/plugins

set PATH=%MVN_HOME%/bin;%PATH%

for /f "tokens=1,2 delims=:" %%E in (deps.txt) do (
  if exist %BUNDLES_HOME%/%%F (
    for /f "tokens=1,2 delims=: " %%G in (%BUNDLES_HOME%/%%F/META-INF/MANIFEST.MF) do (
      if "%%G" == "Bundle-Version" (
        call mvn install:install-file -DgroupId=%%E -DartifactId=%%F -Dversion=%%~nH-SNAPSHOT -DgeneratePom=true -Dpackaging=jar -Dfile="%BUNDLES_HOME%/%%F/target/%%F-%%~nH-SNAPSHOT.jar"
      )
    )
  ) else (
    for %%G in (%ECLIPSE_HOME%/%%F_*.jar) do (
      for /f "tokens=2 delims=_" %%H in ("%%~nG") do (
        call mvn install:install-file -DgroupId=%%E -DartifactId=%%F -Dversion=%%H -DgeneratePom=true -Dpackaging=jar -Dfile="%ECLIPSE_HOME%/%%~nG.jar"
      )
    )
  )
)

它从以下格式的 deps.txt 文件中读取 groupIdartifactId

org.eclipse.ocl:org.eclipse.ocl
org.eclipse.ocl:org.eclipse.ocl.common
org.eclipse.ocl:org.eclipse.ocl.ecore
org.eclipse.ocl:org.eclipse.ocl.pivot

首先它试图在 BUNDLES_HOME 中找到一个包。如果找到,它会从 META-INF/MANIFEST.MF 中读取一个包版本并将 jar 安装到本地 maven 存储库中。生成 pom 文件。

如果在 BUNDLES_HOME 中找不到包,则它会尝试在 ECLIPSE_HOME 中找到它。

第二个脚本读取 deps.txt 并生成 pom.xml 的依赖项列表:

@echo off

set BUNDLES_HOME=C:/Work/workspace-bpms-trunk/bundles
set ECLIPSE_HOME=C:/Tools/eclipse/plugins

break > deps-gen.txt

for /f "tokens=1,2 delims=:" %%E in (deps.txt) do (
  if exist %BUNDLES_HOME%/%%F (
    for /f "tokens=1,2 delims=: " %%G in (%BUNDLES_HOME%/%%F/META-INF/MANIFEST.MF) do (
      if "%%G" == "Bundle-Version" (
        echo        ^<dependency^>>> deps-gen.txt
        echo            ^<groupId^>%%E^</groupId^>>> deps-gen.txt
        echo            ^<artifactId^>%%F^</artifactId^>>> deps-gen.txt
        echo            ^<version^>%%~nH-SNAPSHOT^</version^>>> deps-gen.txt
        echo        ^</dependency^>>> deps-gen.txt
      )
    )
  ) else (
    for %%G in (%ECLIPSE_HOME%/%%F_*.jar) do (
      for /f "tokens=2 delims=_" %%H in ("%%~nG") do (
        echo        ^<dependency^>>> deps-gen.txt
        echo            ^<groupId^>%%E^</groupId^>>> deps-gen.txt
        echo            ^<artifactId^>%%F^</artifactId^>>> deps-gen.txt
        echo            ^<version^>%%H^</version^>>> deps-gen.txt
        echo        ^</dependency^>>> deps-gen.txt
      )
    )
  )
)

Linux 的类似安装程序:

#!/bin/bash

BUNDLES_HOME=~/workspaces/workspace-bpms-trunk/bundles
ECLIPSE_PLUGINS=~/.p2/pool/plugins

while IFS=":" read -r group artifact || [ -n "$p" ]; do
  artifact="${artifact//[$'\r\n']}"
  if [ "$artifact" = "" ]; then
    :
  elif [ -d "$BUNDLES_HOME/$artifact" ]; then
    while IFS=":" read -r key value || [ -n "$p" ]; do
      if [ "$key" = "Bundle-Version" ]; then
        version="${value//[[:space:]]/}"
        version="${version/.qualifier/-SNAPSHOT}"
        mvn install:install-file -DgroupId=$group -DartifactId=$artifact \
          -Dversion=$version -DgeneratePom=true -Dpackaging=jar \
          -Dfile="$BUNDLES_HOME/$artifact/target/$artifact-$version.jar"
      fi
    done < "$BUNDLES_HOME/$artifact/META-INF/MANIFEST.MF"
  else
    for file in "$ECLIPSE_PLUGINS"/${artifact}_*.jar; do
      version="${file%%.jar}"
      version="${version##*_}"
      mvn install:install-file -DgroupId=$group -DartifactId=$artifact \
        -Dversion=$version -DgeneratePom=true -Dpackaging=jar -Dfile="$file"
    done
  fi
done < deps.txt

和 pom 文件依赖生成器:

#!/bin/bash

BUNDLES_HOME=~/workspaces/workspace-bpms-trunk/bundles
ECLIPSE_PLUGINS=~/.p2/pool/plugins

: > deps-gen.txt

while IFS=":" read -r group artifact || [ -n "$p" ]; do
  artifact="${artifact//[$'\r\n']}"
  if [ "$artifact" = "" ]; then
    echo >> deps-gen.txt
  elif [ -d "$BUNDLES_HOME/$artifact" ]; then
    while IFS=":" read -r key value || [ -n "$p" ]; do
      if [ "$key" = "Bundle-Version" ]; then
        version="${value//[[:space:]]/}"
        version="${version/.qualifier/-SNAPSHOT}"
        echo "        <dependency>" >> deps-gen.txt
        echo "            <groupId>$group</groupId>" >> deps-gen.txt
        echo "            <artifactId>$artifact</artifactId>" >> deps-gen.txt
        echo "            <version>$version</version>" >> deps-gen.txt
        echo "        </dependency>" >> deps-gen.txt
      fi
    done < "$BUNDLES_HOME/$artifact/META-INF/MANIFEST.MF"
  else
    for file in "$ECLIPSE_PLUGINS"/${artifact}_*.jar; do
      version="${file%%.jar}"
      version="${version##*_}"
      echo "        <dependency>" >> deps-gen.txt
      echo "            <groupId>$group</groupId>" >> deps-gen.txt
      echo "            <artifactId>$artifact</artifactId>" >> deps-gen.txt
      echo "            <version>$version</version>" >> deps-gen.txt
      echo "        </dependency>" >> deps-gen.txt
    done
  fi
done < deps.txt
