AppEngine Endpoints Issue?

[Paul Mazzuca]

When running the following EndPoints example with GAE 1.9.37 as so,

git clone https://github.com/GoogleCloudPlatform/appengine-endpoints-helloworld-java-maven

#change the version in the POM to 1.9.37

mvn appengine:devserver

I receive the following error:

[ERROR] Failed to execute goal com.google.appengine:appengine-maven-plugin:1.9.37:endpoints_get_discovery_doc (default) on project helloworld: Execution default of goal com.google.appengine:appengine-maven-plugin:1.9.37:endpoints_get_discovery_doc failed: A required class was missing while executing com.google.appengine:appengine-maven-plugin:1.9.37:endpoints_get_discovery_doc: com/google/appengine/repackaged/com/google/api/client/repackaged/org/apache/commons/codec/binary/StringUtils

Could an essential EndPoints class have been removed in the latest GAE release, or am I missing something?

I got same problem when using GAE java 1.9.37.

It is work with GAE java 1.9.34 before.

After compare source of com.google.appengine.repackaged.com.google.api.client.util.StringUtils , I found it is a little different.

In 1.9.34

package com.google.appengine.repackaged.com.google.api.client.util;

public class StringUtils {
    public static final String LINE_SEPARATOR = System.getProperty("line.separator");

    public static byte[] getBytesUtf8(String string) {
        return com.google.appengine.repackaged.org.apache.commons.codec.binary.StringUtils.getBytesUtf8(string);
    }

    public static String newStringUtf8(byte[] bytes) {
        return com.google.appengine.repackaged.org.apache.commons.codec.binary.StringUtils.newStringUtf8(bytes);
    }

    private StringUtils() {
    }
}

In 1.9.37

package com.google.appengine.repackaged.com.google.api.client.util;

public class StringUtils {
    public static final String LINE_SEPARATOR = System.getProperty("line.separator");

    public static byte[] getBytesUtf8(String string) {
        return com.google.appengine.repackaged.com.google.api.client.repackaged.org.apache.commons.codec.binary.StringUtils.getBytesUtf8(string);
    }

    public static String newStringUtf8(byte[] bytes) {
        return com.google.appengine.repackaged.com.google.api.client.repackaged.org.apache.commons.codec.binary.StringUtils.newStringUtf8(bytes);
    }

    private StringUtils() {
    }
}

And I can not find com.google.appengine.repackaged.com.google.api.client.repackaged.org.apache.commons.codec.binary.StringUtils in GAE java 1.9.37

I think this is why it can't work.

Is this a bug or something I miss when upgrade to GAE java 1.9.37 ?

[Paul Mazzuca]

I think this is a bug in GAE. I also think that it can affect deployed instances since GAE uses the latest version in production.  I would be interested in knowing if there is a workaround or if we have to wait for the next version?

[ludovic Champenois]

Investigating,
Thanks for the detailled info,
Ludo

        return com.google.appengine.repackaged.org.apache.commons.codec.binary.StringUtils.newStringUtf8(bytes

);<

    }

    private StringUtils() {

}

In 1.9.37

package com.google.appengine.repackaged.com.google.api.client.util;

public class StringUtils {
    public static final String LINE_SEPARATOR = System.getProperty("line.separator");

    public static byte[] getBytesUtf8(String string) {

Any updates on this issue?  Any guidance?

[Olukorede Aguda]

Also facing this issue. Any update? It doesn't help that we're running into this while evaluating adoption of AppEngine :(

[ludovic Champenois]

I think the issue got fixed in 1.9.38 that should be out shortly.
Meanwhile, you can revert to 1.9.36,
Ludo
