Maven`help：effective-pom`仅为单个项目而非所有项目生成 [英] Maven `help:effective-pom` only generating for a single project, not all projects

问题描述

我想为多模块构建中的所有子项目生成有效的pom。

I want to generate an effective pom for all the subprojects in a multi-module build.

help：effective-pom 文档此处州

它将遍历当前构建会话中的所有项目，为每个项目打印有效的POM

It will iterate over all projects in the current build session, printing the effective POM for each

我在 mvn help：effective-pom ： //github.com/uklance/gradle-maven-transform/tree/master/example/maven-root\"rel =nofollow noreferrer>这个maven项目它只生成根，而不是子项目。

I'm running mvn help:effective-pom in the root directory of this maven project and it's only generating for the root and not for the subprojects.

为什么不为所有项目生成有效的pom。注意：我有另一个真实世界的maven项目，其中 mvn help：effective-pom 正确生成< projects> 标记与每个子模块的嵌套< project> 。我不确定为什么它不适用于这个maven项目

Why isn't the effective pom being generated for all projects. Note: I have another real world maven project where mvn help:effective-pom is correctly generating a <projects> tag with nested <project> for each submodule. I am unsure why it is not working for this maven project

这是生成的有效pom

Here is the effective pom generated

推荐答案

我最终得到了一个不同的解决方案。我不是接受单个根 pom.xml 作为输入，而是要求解析 pom.xml 的集合。我现在还嵌入 maven-model-builder 并通过 DefaultModelBuildingRequest <调用 DefaultModelBuilder / code>

I ended up with a different solution in the end. Rather than accepting a single root pom.xml as input, I instead require a collection of pom.xml to be resolved. I also now embed the maven-model-builder and invoke the DefaultModelBuilder via a DefaultModelBuildingRequest

例如：

DefaultModelBuilderFactory factory = new DefaultModelBuilderFactory();
DefaultModelBuilder builder = factory.newInstance();
ModelBuildingRequest req = new DefaultModelBuildingRequest();
req.setProcessPlugins(false);
req.setModelResolver(createModelResolver());
req.setValidationLevel(ModelBuildingRequest.VALIDATION_LEVEL_MINIMAL);
for (File pomFile : pomFiles) {
   req.setPomFile(pomFile);
   Model effectivePom = builder.build(req).getEffectiveModel();
   ...
}
