修改 ivy 类路径条目

Question

在下图中，我想要

1. Ivy 设置路径不包括 ${ivyproject_loc}
2. 不包括 ${project_loc} 的属性文件

这就是我现在所拥有的。我在想删除 ivy 库并按照我想要的方式添加它可能会更容易。我知道如何添加，但最好的删除方法是什么？

protected void changeIvyClasspath(IProject project) throws CoreException {

    if(project.hasNature(JavaCore.NATURE_ID)){
        IJavaProject jproject = JavaCore.create(project);
        IClasspathEntry[] entries = jproject.getRawClasspath();
        for (IClasspathEntry entry : entries) {
            if(entry.toString().contains("org.apache.ivyde.eclipse.cpcontainer.IVYDE_CONTAINER")){
                if(entry.toString().contains("project_loc") || entry.toString().contains("ivyproject_loc")){
                    //how to remove entry?

                    addIvyToClasspath();
                }
            }
        }
    }
}

我尝试过的其他方法是修改现有设置，但没有奏效。

这是尝试这样做的代码：

protected void changeIvyClasspath(IProject project) throws CoreException {

    if(project.hasNature(JavaCore.NATURE_ID)){
        IJavaProject jproject = JavaCore.create(project);
        IClasspathEntry[] entries = jproject.getRawClasspath();
        for (IClasspathEntry entry : entries) {
            if(entry.toString().contains("org.apache.ivyde.eclipse.cpcontainer.IVYDE_CONTAINER")){
                if(entry.toString().contains("project_loc") || entry.toString().contains("ivyproject_loc")){
                    IvyClasspathContainer ivycp = IvyClasspathContainerHelper.getContainer(entry.getPath(), jproject);
                    IvyClasspathContainerConfiguration conf = new IvyClasspathContainerConfiguration(jproject, "ivy.xml", true);
                    SettingsSetup ss = conf.getIvySettingsSetup();
                    List<String> props = new ArrayList<String>();
                    props.add("project.properties");
                    props.add(".properties/eclipse.properties");
                    ss.setPropertyFiles(props);
                    conf.setIvySettingsSetup(ss);
                    ss.setIvySettingsPath(".properties/ivysettings.xml");
                    ivycp.setConf(conf);
                    ivycp.launchResolve(false, null);
                }
            }
        }
    }
}

通过该项目，您可以获得所有类路径条目。我经历并排除了常春藤条目。然后我用正确的类路径和属性文件重新添加了它们。现在，路径不包括 ${ivyproject_loc} 和 ${project_loc}。

代码如下：

protected void changeIvyClasspath(IProject project, IProgressMonitor monitor) throws CoreException {

    if(project.hasNature(JavaCore.NATURE_ID)){
        IJavaProject jproject = JavaCore.create(project);
        List<IClasspathEntry> iClasspathEntryList = new ArrayList<IClasspathEntry>();

        IClasspathEntry[] entries = jproject.getRawClasspath();
        for (IClasspathEntry entry : entries) {
            //exclude ivy.xml entries
            if (!entry.getPath().toString().contains("ivy.xml")) {
                iClasspathEntryList.add(entry);
            } 
        }

        //Add the ivy entries with the correct class path
        addIvyToClasspath(new String[] { "compile", "runtime" }, true, iClasspathEntryList, project, jproject, monitor);
        addIvyToClasspath(new String[] { "provided", "test" }, false, iClasspathEntryList, project, jproject, monitor);

        entries = iClasspathEntryList.toArray(new IClasspathEntry[iClasspathEntryList.size()]);

        jproject.setRawClasspath(entries, jproject.getOutputLocation(), null);
    }
}
