I am using vscode-java with selenium project.
After I cloned form https://github.com/SeleniumHQ/selenium.git,
I create 2 pom.xml files, one for /selenium/java/client, one for /selenium/java/server, as below.

pom.xml for client

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.seleniumhq</groupId>
  <artifactId>client</artifactId>
  <version>2.52.0</version>
  <build>
    <directory>${project.basedir}/build</directory>
    <outputDirectory>${project.build.directory}/production</outputDirectory>
    <sourceDirectory>src</sourceDirectory>
    <testSourceDirectory>test</testSourceDirectory>
  </build>
</project>

pom.xlm for server

<project>
  <parent>
    <groupId>org.seleniumhq</groupId>
    <artifactId>client</artifactId>
    <version>2.52.0</version>
    <relativePath>../client/pom.xml</relativePath>
  </parent>
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.seleniumhq</groupId>
  <artifactId>server</artifactId>
  <version>2.52.0</version>
  <build>
    <directory>${project.basedir}/build</directory>
    <outputDirectory>${project.build.directory}/production</outputDirectory>
    <sourceDirectory>src</sourceDirectory>
    <testSourceDirectory>test</testSourceDirectory>
  </build>
</project>

when I open a java file in the server project, everything works well,
but when I open a java file in the client project,
PM Problem encountered like below.

    Did you open vscode before or after creating the pom.xml files?

    Yes, I opened vscode before and after creating the pom.xml file.
    I create those 2 pom.xml by vscode, after editing, I closed vscode, and restarted it.

    .project and .classpath were in the git repository, after open vscode with java extension,
    .project and .classpath have been changed.

    since filteredResources is not supported,
    I deleted filteredResources block, so the server project can work, but not the client.

    <filteredResources>
        <filter>
            <id>1350421599384</id>
            <name></name>
            <type>26</type>
            <matcher>
                <id>org.eclipse.ui.ide.multiFilter</id>
                <arguments>1.0-name-matches-false-false-.svn</arguments>
            </matcher>
        </filter>
        <filter>
            <id>1350421599386</id>
            <name></name>
            <type>6</type>
            <matcher>
                <id>org.eclipse.ui.ide.multiFilter</id>
                <arguments>1.0-name-matches-false-false-build.desc</arguments>
            </matcher>
        </filter>
</filteredResources>
