gradle - 自定义Gradle插件可解决Ivy依赖项

转载作者：行者123 更新时间：2023-12-03 06:23:51

我正在编写扩展URLResolver的gradle插件，但遇到了问题。

我们有一个将多个库 bundle 在一起的项目，该 bundle 包在映射文件中指定组成库的版本，而在依赖项文件中，我们指定“默认”的版本，除非我们要使用特定的库版本。

目前，所有这些都在build.gradle文件中定义，直到可以将其重构为独立插件为止。

我的插件代码如下:

class DefaultURLResolverPlugin implements Plugin<Project> {
    void apply(Project project) {
        project.convention.plugins.DefaultURLResolverPluginConvention = new DefaultURLResolverPluginConvention(project.ver.MsParts)
    }
}

class DefaultURLResolverPluginConvention {
    private final String partsVersion;

    public DefaultURLResolverPluginConvention(String partsVersion) {
        this.partsVersion = partsVersion
    }

    public DefaultURLResolver newDefaultURLResolver() {
        return new DefaultURLResolver(partsVersion)
    }
}

import java.text.ParseException

class DefaultURLResolver extends org.apache.ivy.plugins.resolver.URLResolver {

    Map versionMapping = new HashMap()

    public DefaultURLResolver(String partsVersion) {
        File defaulstFile = new File("/parts/" + partsVersion + "/etc/bundles/library-versions.default.properties")
        for (String line : defaulstFile.readLines()) {
            if (line.length() > 0 && !line.startsWith('#')) {
                String[] mapping = line.split('=')
                versionMapping.put(mapping[0], mapping[1])
            }
        }
    }

    @Override
    public org.apache.ivy.core.resolve.ResolvedModuleRevision getDependency(org.apache.ivy.core.module.descriptor.DependencyDescriptor dd, org.apache.ivy.core.resolve.ResolveData data)
    throws ParseException
    {
        org.apache.ivy.core.module.descriptor.DependencyDescriptor lookup = dd
        if ("default".equals(dd.getDependencyRevisionId().getRevision())) {
            org.apache.ivy.core.module.id.ModuleRevisionId moduleRevisionId = dd.getDependencyRevisionId()
            String key = moduleRevisionId.getOrganisation() + "." + moduleRevisionId.getName() + ".version.default"
            println "looking for key " + key + " found: " + versionMapping.get(key)
            org.apache.ivy.core.module.id.ModuleRevisionId defaultedRevisionId = org.apache.ivy.core.module.id.ModuleRevisionId.intern(new org.apache.ivy.core.module.id.ModuleRevisionId(
                org.apache.ivy.core.module.id.ModuleId.newInstance(moduleRevisionId.getOrganisation(), moduleRevisionId.getName()), versionMapping.get(key)))
            lookup = dd.clone(defaultedRevisionId)
        }
        return super.getDependency(lookup, data);
    }
}

依赖项解析可以很好地找到正确的ivy.xml文件，但是随后我得到了NullPointerException，大概是在它试图查找实际的jar时。我正在寻找的是一些有关资源的指针，这些资源将告诉我如何修复它，很明显，如果有人可以告诉我解决方案会很棒。 :-)

我得到的stacktrace是:
