我正在尝试使用Equinox p2 API来获取p2存储库的内容。
IMetadataRepositoryManager manager = (IMetadataRepositoryManager) agent
.getService(IMetadataRepositoryManager.SERVICE_NAME);
IArtifactRepositoryManager artifactManager = (IArtifactRepositoryManager) agent
.getService(IArtifactRepositoryManager.SERVICE_NAME);
manager.addRepository(new URI(repoURL));
artifactManager.addRepository(new URI(repoURL));
SubMonitor progressSubMonitor = SubMonitor.convert(progressMonitor, 100);
IMetadataRepository metadataRepo = manager.loadRepository(new URI(repoURL), progressSubMonitor.split(50));
执行loadRepository操作时，它将始终使用JAVA_HOME中配置的Java版本，因此它将在该特定位置搜索证书。但是，如果在JAVA_HOME中配置了未安装证书的版本，则会出现以下错误。

我要实现的目标，因为我正在构建eclipse RCP产品，因此它将使用在Windows-> Preferences-> Installed Jres中配置的Java版本。我知道如何从首选项中获取Java版本，但是我找不到一种方法来强制获取p2存储库以使用该特定版本的Java或至少在该版本中找到的证书。
到目前为止，我尝试过但没有成功：
KeyStore ks = KeyStore.getInstance("JKS");
File file = new File(path_to_cacerts_file);
ks.load(new FileInputStream(file), "changeit".toCharArray());
TrustManagerFactory trustManagerFactory =
TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init(ks);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, trustManagerFactory.getTrustManagers(), null);
