【问题描述】:
我们的主要项目是“common-core”,一个 Ant 项目。此代码库正在不断开发中。
我们有另一个项目“batch”,它是一个 Maven 项目。在这个项目中,我们希望使用“common-core”作为依赖项。
我试过在 pom 文件中做这样的事情:
<dependency>
<groupId>mydomain</groupId>
<artifactId>ibcore-with-dependencies</artifactId>
<version>current</version>
<scope>system</scope>
<systemPath>${project.basedir}/../common-core/bin/common-core-with-dependencies.jar</systemPath>
</dependency>
...
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>validate</id>
<phase>validate</phase>
<configuration>
<tasks>
<touch file="${project.basedir}/../common-core/bin/common-core-with-dependencies.jar" mkdirs="true" />
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
<execution>
<id>clean</id>
<phase>clean</phase>
<configuration>
<tasks>
<exec dir="${project.basedir}/../common-core/build" executable="ant" failonerror="true">
<arg line="clean" />
</exec>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
<execution>
<id>build</id>
<phase>process-resources</phase>
<configuration>
<tasks>
<exec dir="${project.basedir}/../common-core/build" executable="ant" failonerror="true">
<arg line="single-jar" />
</exec>
<copy todir="${project.build.directory}/lib"
file="${project.basedir}/../common-core/bin/common-core-with-dependencies.jar" />
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
但这不起作用,因为如果在构建开始之前common-core-with-dependencies.jar 不存在,验证步骤将失败。也就是说,touch 命令发生得太晚了。
process-resources 阶段的 ant 任务构建 common-core 并创建一个包含 common-core 及其依赖项的一体化 jar。
有没有办法让验证步骤不会因为缺少 common-core-dependencies.jar 而失败,或者在 validate 之前执行一个 ant 步骤?
我有一个变通方法,将 mvn build 命令包装在一个脚本中,该脚本在 common-core-with-dependencies.jar 上执行 touch,但我希望避免这种情况。
编辑:
我使用 Blaine 的回答所链接的信息得到了一些工作,但它最终仍然相当复杂。
common-core 有一个包含构建和测试依赖项的 lib 目录。这些可能与 Maven 选择的版本不同,但众所周知它们可以工作,所以这就是我想要的。
我在common-core(用于构建和测试构建)中添加了两个新的 Ant 目标,它们创建了包含所有依赖 jar(或测试 jar)内容的超级 jar 文件。
不幸的是,这有很多问题:
一些罐子已签名。我必须从 META-INF 中删除签名文件
各种 spring jar 都包含相同的 META-INF/spring.* 文件。这些需要结合起来。我努力让 Ant 处理这些重复的名称,但最终还是做了一些修改。
蚂蚁目标代码:
<target name="single-jar" depends="build"
description="Produce a single jar containing core-common plus all its dependencies for use by batch">
<jar destfile="${core-depends.jar}-temp" filesetmanifest="merge">
<fileset file="${core.jar}" includes="**/*.class"/>
<fileset dir="${core.src}" includes="**/*.properties" />
<zipgroupfileset dir="${core.lib}">
<include name="**/*.jar" />
<exclude name="notdeployed/**/*.jar" />
</zipgroupfileset>
</jar>
<!-- The combined jar file contains multiple instances of various spring.* files.
Many of these need to be concatenated into a single instance.
The only way I can think of to do this is to extract them with distinct names
before concatenating them -->
<delete dir="${core.bin}/spring" quiet="true"/>
<unzip src="${core-depends.jar}-temp" dest="${core.bin}/spring">
<patternset>
<include name="META-INF/spring.*"/>
</patternset>
<scriptmapper language="javascript">
self.addMappedName(source + '.' + (Math.random()));
</scriptmapper>
</unzip>
<mkdir dir="${core.bin}/spring"/> <!-- In case there was nothing to unzip -->
<concat destfile="${core.bin}/spring.schemas" fixlastline="true">
<fileset dir="${core.bin}/spring" includes="META-INF/spring.schemas.*" />
</concat>
<concat destfile="${core.bin}/spring.factories" fixlastline="true">
<fileset dir="${core.bin}/spring" includes="META-INF/spring.factories.*" />
</concat>
<concat destfile="${core.bin}/spring.handlers" fixlastline="true">
<fileset dir="${core.bin}/spring" includes="META-INF/spring.handlers.*" />
</concat>
<concat destfile="${core.bin}/spring.tooling" fixlastline="true">
<fileset dir="${core.bin}/spring" includes="META-INF/spring.tooling.*" />
</concat>
<jar destfile="${core-depends.jar}">
<zipfileset dir="${core.bin}" prefix="META-INF/" includes="spring.*" />
<zipfileset src="${core-depends.jar}-temp" excludes="META-INF/spring.schemas META-INF/spring.handlers META-INF/spring.factories META-INF/spring.tooling META-INF/**/*.SF, META-INF/**/*.DSA, META-INF/**/*.RSA"/>
</jar>
<delete dir="${core.bin}/spring" quiet="true"/>
<delete file="${core-depends.jar}-temp" />
<delete quiet="true">
<fileset dir="${core.bin}" includes="spring.*"/>
</delete>
</target>
