Example 1 with InputStreamProvider

use of com.google.idea.blaze.base.io.InputStreamProvider in project intellij by bazelbuild.

the class JavaSourcePackageReader method getDeclaredPackageOfJavaFile.

@Override
@Nullable
public String getDeclaredPackageOfJavaFile(BlazeContext context, ArtifactLocationDecoder artifactLocationDecoder, SourceArtifact sourceArtifact) {
    if (sourceArtifact.artifactLocation.isGenerated()) {
        return null;
    }
    InputStreamProvider inputStreamProvider = InputStreamProvider.getInstance();
    File sourceFile = artifactLocationDecoder.decode(sourceArtifact.artifactLocation);
    try (InputStream javaInputStream = inputStreamProvider.getFile(sourceFile)) {
        BufferedReader javaReader = new BufferedReader(new InputStreamReader(javaInputStream, UTF_8));
        String javaLine;
        while ((javaLine = javaReader.readLine()) != null) {
            Matcher packageMatch = PACKAGE_PATTERN.matcher(javaLine);
            if (packageMatch.find()) {
                return packageMatch.group(1);
            }
        }
        IssueOutput.warn("No package name string found in java source file: " + sourceFile).inFile(sourceFile).submit(context);
        return null;
    } catch (FileNotFoundException e) {
        IssueOutput.warn("No source file found for: " + sourceFile).inFile(sourceFile).submit(context);
        return null;

Example 2 with InputStreamProvider

use of com.google.idea.blaze.base.io.InputStreamProvider in project intellij by bazelbuild.

    Map<ArtifactLocation, String> outputMap = Maps.newHashMap();
    InputStreamProvider inputStreamProvider = InputStreamProvider.getInstance();
    try (InputStream input = inputStreamProvider.getFile(packageManifest)) {
