[MRESOLVER-98] resolver ant task doesn't obey dependencyManagement

[lwr]

https://issues.apache.org/jira/browse/MRESOLVER-98

[lwr]

After applying the patch, the resolving mechanism still does not work as expected

test case

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.apache.maven.resolver</groupId>
        <artifactId>maven-resolver-api</artifactId>
        <version>1.4.1</version>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.apache.maven.resolver</groupId>
      <artifactId>maven-resolver-util</artifactId>
      <version>1.4.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

the dependency tree

[INFO] \- org.apache.maven.resolver:maven-resolver-util:jar:1.4.1:test
[INFO]    \- org.apache.maven.resolver:maven-resolver-api:jar:1.4.1:test

but the resolver will incorrectly resolve maven-resolver-api as compile scope

I think it would be caused by the resolver itself, will 1.4.2 resolve this problem?

[lwr]

I had add the testcase to expose this problem

the resolver will incorrectly resolve maven-resolver-api as compile scope

您好，咨询下，还没编译您这个版本。
我发现比如springtext他自带mockito这种，我们在properties里指定了版本，在用实际maven的过程当中没问题，但在ant中用-verbose可以看出他用的版本是有问题的是因为您这个原因么？

另外发现如果有版本在仓库是snapshot模式的，带时间戳和buildnumber的也会报错，和这个相关么？

@snoopyhzy I have abandon this project as a solution of maven ant integration

this PR fixes the DependencyManagement version issue but still have the scope issue, so I think the maven resolver is not a stable solution I can rely on this time.

Now I switch back to use the deprecated maven-ant-task project, with a little patch

<!-- patch super pom to workaround central repo policy change problem (http access forbidden) -->
<unzip src="path/to/maven-ant-task-2.1.3.jar"
   dest="maven/target/workaround-central-repo-https">
    <patternset includes="**/pom-4.0.0.xml" />
</unzip>
<replace dir="maven/target/workaround-central-repo-https" encoding="utf8"
     token="http://repo1.maven.org/maven2" value="https://repo1.maven.org/maven2" />
<typedef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant">
    <classpath path="maven/target/workaround-central-repo-https" />
    <classpath path="path/to/maven-ant-task-2.1.3.jar" />
</typedef>

@lwr thank you
I used the project last week,but find a fatal problem that I cannot slove.The problm is https://issues.apache.org/jira/plugins/servlet/mobile#issue/MANTTASKS-251 ,and My company cannot acesss Internet.
So I use this project instend.

I use this project to download java libs and then run inc test case.

Now I find another solusion that is use exec cmd.exe /c mvn dependency:copy-dependencies -Doutputdir.
It can solve my problem and dependent orginial maven

[lwr]

@snoopyhzy that project is already retired, no any issue reporting will be fixed and has no meaning.

I had found the same problem what you reported I in https://issues.apache.org/jira/browse/MANTTASKS-251

That issue only occurs while processing dependency with type=import (mirror not being applied), in most situations that is not a problem until recently that http://repo1.maven.org being shutdown (enforcing https accessing).

We have several choices:

1. first I try maven-resolver-ant-tasks and now I am being here
2. secondly I try patch the super pom as last comment, and that works.
3. meanwhile run command mvn dependency:resolve before the ant execution, would help workaround the download problem, both "central repo http problem" and "mirror problem"

   mvn dependency:resolve -s settings.xml

[snoopyhzy]

@lwr thank you,But I am sure it is the problem of maven-resolver-ant-tasks

[lwr]

@snoopyhzy it is problem of retired project maven-ant-tasks not this new project maven-resolver-ant-tasks, they are different and this project is the replacement of the retired one

[snoopyhzy]

@lwr the new one has two other problem that I find.
One is it download error version of dependencies.
for example,I use springboot test and set mockito version in properties.The version download different with use mvn copy-dependencies and the ant plugin.
Another is it do not support Snapshot version with timestamp and serialno

[lwr]

@snoopyhzy I had said that why I am here for, this project maven-resolver-ant-tasks is not workable.

this PR fixes one (dependency management version problem), but another not fixed yet (see the new committed test case testResolvePomWithScopedAndManagement). So, my suggestion is

1. stay use the retired maven-ant-tasks project
2. with patching it's embedded super pom-4.0.0.xml
3. run mvn dependency:resolve before the ant task run so all download problems could be avoided

[snoopyhzy]

@lwr OIC,you mean use resolve to download all jar to local repo

[michael-o]

@lwr Can you rebase on top of master? I'd like to pick this up.

[michael-o]

Please hav a look at DefaultProjectDependenciesResolver in Maven Core. There you will find the code how Maven prepares the collect request. I strongly assume that those code bases are disjoint and therefore you see the erratic behavior.

[lwr]

we had give-up using maven-resolver, try this https://gist.github.com/lwr/6829cefaab2261cec1cc733f6398b9ac

[michael-o]

Closing this since is not going to be fixed.
