Question

我正在尝试从源

构建JIRA 6.0.7

https://confluence.atlassian.com/jira064/building-jira-from-source-720411927.html

它与JDK-8构建了问题，所以我不得不使用JDK-7。一个工件下载最新的插件版本（虽然在pom.xml中定义了显式版本）并且由于类文件版本而失败。

以下是mvn -X package的输出：

注意

maven-amps-plugin-4.1.5.jar是为java 6构建的：

C:\>javap -v -classpath maven-amps-plugin-4.1.5.jar com.atlassian.maven.plugins.amps.osgi.ValidateTestManifestMojo | find "major version"
  major version: 50

注2

我非常绝望，我现在正在调试maven代码。 https://maven.apache.org/ref/3.3.1/xref/org/apache/maven/plugin/version/internal/DefaultPluginVersionResolver.html#L90

在回到resolveFromRepository()之前，它会尝试resolveFromProject()，但会失败，因为request.pom == null。为什么呢？

project.getBuildPlugins（）使用maven-amps-plugin返回（在众多中）version == null。为什么呢？

project.getBuildPlugins().get(0)
    artifactId  "maven-jira-plugin" (id=489)    
    version "4.1.5" (id=498)    

project.getBuildPlugins().get(5)
    artifactId  "maven-amps-plugin" (id=402)    
    version null

最初，在解析Plugin时使用正确的版本创建com/atlassian/amps/standalone/4.1.5/standalone-4.1.5.pom对象，但在DefaultLifecyclePluginAnalyzer.parseLifecyclePhaseDefinitions()中创建另一个实例。我想这是由<packaging>atlassian-plugin</packaging>

引起的

似乎maven-amps-plugin 4.1.5，maven-jira-plugin的依赖关系是使用JDK 8构建的。我试图尝试我可以获得的版本，希望是以前的版本。奇怪的是，Maven Central从2015年开始有5.0.18，所以我对它感到厌烦，最终出现了Oracle驱动程序的问题，这是好的（因为Oracle驱动程序，如果我没有记错的话，不会存储在Central上）。您的本地存储库可能拥有它，此代码段可以帮助您。因此，即使不太可能正确解决您的问题，以防万一。

        <plugin>
            <groupId>com.atlassian.maven.plugins</groupId>
            <artifactId>maven-jira-plugin</artifactId>
            <version>4.1.5</version>
            <extensions>true</extensions>
            <dependencies>
                <dependency>
                    <groupId>com.atlassian.maven.plugins</groupId>
                    <artifactId>maven-amps-plugin</artifactId>
                    <version>5.0.18</version>
                </dependency>
            </dependencies>
        </plugin>

插件版本解析两次，第二次错误版本已解决
